Authorized police and other law-enforcement officers act under the laws of the country where the person is located, while prosecutors and courts may authorize or review detention, and INTERPOL coordinates internationally without independent arrest powers.
WASHINGTON, DC, September 25, 2026: The power to arrest someone named in an INTERPOL Red Notice belongs to officials authorized under the law of the jurisdiction where the person is encountered, rather than to INTERPOL as an international organization.
Depending upon the country, those officials may include national police, regional or municipal officers, border police, immigration enforcement personnel, or specialized fugitive units, each operating within statutory powers and procedures that determine when an arrest is lawful.
Prosecutors and courts perform different functions because prosecutors may request warrants or detention orders, while judges may authorize custody, review its legality, and examine extradition requirements without personally carrying out the physical arrest at an airport or residence.
The distinction matters whenever a headline says someone was “arrested by INTERPOL,” because that description commonly compresses several separate actions involving an international alert, national investigators, authorized arresting officers, prosecutors, and judicial or executive decision-makers.
INTERPOL Coordinates Cooperation
A Red Notice requests that countries locate and provisionally arrest an identified person pending extradition, surrender, or similar legal action, usually based on an arrest warrant or judicial order issued in the country requesting international assistance.
Publication makes the request available through international police channels, but it does not transfer the issuing country’s police powers abroad or create a universally enforceable order requiring every foreign officer to arrest the person immediately.
The receiving country determines its legal significance, including whether officers need a domestic warrant, a formal provisional-arrest request, additional documentation, or another recognized basis before restricting the person’s liberty beyond an initial examination.
The same notice can therefore produce different responses in different jurisdictions, with one country allowing immediate provisional arrest and another requiring further legal steps before police can act on the foreign request.
Support Teams Have No Independent Arrest Mandate
Saying that INTERPOL can never deploy personnel would be inaccurate, because the organization can send specialized experts to assist member countries with incidents, investigations, identification work, and security arrangements when the relevant national authorities request support.
INTERPOL’s description of its specialist response teams explains that these deployments provide investigative, analytical, forensic, and database assistance, helping national agencies perform their work without creating a separate international force empowered to arrest people independently.
An INTERPOL-supported operation can therefore involve personnel working alongside national officers, sharing information and technical expertise, while the officers legally responsible for an arrest remain subject to the host jurisdiction’s authority and procedures.
If a participating officer also holds domestic police powers, those powers arise from that officer’s national position and applicable law, rather than from the mere presence of an INTERPOL badge, assignment, database connection, or operational partnership.
The Original Warrant Belongs to the Requesting Jurisdiction
The underlying case normally begins with investigators, prosecutors, and judicial authorities operating within one country, where an arrest warrant or court order establishes that a person is sought for prosecution or enforcement of a sentence.
That warrant remains part of the originating legal system, even after information about it circulates internationally, and its existence does not ordinarily allow the requesting country’s officers to enter another jurisdiction and execute it themselves.
For example, investigators who learn that a wanted defendant is living overseas may share evidence and location information with foreign partners, but the law of the country where the defendant resides controls the arrest conducted there.
The issuing court’s order and the receiving country’s arrest authority are therefore separate legal questions, although the first may provide essential supporting information for obtaining the second through an extradition treaty or another recognized procedure.
Which Police Officers Can Make the Arrest?
National police agencies often handle international fugitive matters, but regional, state, provincial, or municipal officers may also participate when their domestic powers permit them to execute the relevant warrant or take an authorized person into custody.
The officer who first encounters the person may differ from the officer who ultimately makes the arrest, particularly when a routine identity check requires confirmation from a specialized unit or consultation with an extradition prosecutor.
A traffic officer might discover a possible match and request assistance, while a national fugitive team confirms the information and executes a domestic warrant issued in connection with the foreign request for provisional arrest.
The agency’s title alone does not settle the question, because the relevant inquiry concerns the officer’s jurisdiction, statutory powers, applicable warrant, required approvals, and compliance with the procedures governing that particular form of detention.
Border Agencies Have Different Powers
At an airport, seaport, or land crossing, border personnel may discover the notice while checking a passport, reviewing passenger information, examining immigration records, or comparing the traveler’s identity with national and international police data.
Some border agencies employ officers with criminal arrest powers, while others primarily exercise inspection and immigration functions and must refer a wanted-person match to police or another agency authorized to carry out an extradition arrest.
The traveler may initially be directed to secondary inspection while officials verify identity and seek guidance, but that temporary examination should not automatically be described as formal extradition custody without identifying the authority actually being exercised.
Amicus International Consulting’s discussion of passport security features provides background on document verification and helps explain how an identity check can begin the encounter before officials determine whether separate police information supports further legal action.
Prosecutors Connect the Foreign Request With Domestic Procedure
Prosecutors may assess whether the requesting country has supplied enough information to seek provisional arrest, including details identifying the person, describing the alleged offense, confirming the foreign warrant, and explaining the intended extradition request.
Where a domestic judicial order is required, a prosecutor or other designated authority may apply to the competent court, presenting the materials required under national legislation and the applicable international arrangement.
The prosecutor does not ordinarily retry the foreign criminal case at this preliminary stage, but must address the requirements governing the requested action rather than assuming that an INTERPOL entry makes every legal condition unnecessary.
In some legal systems, prosecutors can direct certain investigative or custodial measures themselves, which is another reason the precise division of responsibility must be determined under local law rather than through generalized worldwide assumptions.
Courts Authorize and Review Custody
A court may become involved before an arrest by issuing a domestic warrant, or afterward by reviewing an urgent arrest that officers were legally entitled to make without prior judicial authorization under the applicable national procedure.
Judicial review can address whether the person has been correctly identified, whether the necessary legal conditions exist, whether detention remains justified, and whether the governing extradition framework provides for release or conditions restricting movement.
Courts may also examine challenges to the manner or duration of custody, although the scope of review and the available remedies differ between countries and may depend upon the distinction between provisional detention and formal extradition proceedings.
A judge’s order authorizing continued detention does not necessarily approve eventual surrender, because the requesting government may still need to submit additional documents and satisfy further requirements before extradition can lawfully take place.
The National Central Bureau Provides Coordination
Each member country’s National Central Bureau serves as an important link between domestic agencies, INTERPOL’s General Secretariat, and foreign police counterparts, helping information move through official channels when a wanted person is located.
The bureau may verify the notice, contact the requesting country, relay updated identifying information, clarify operational instructions, or connect frontline officers with the national authorities responsible for extradition and international criminal cooperation.
Some bureau personnel may also be sworn officers with domestic enforcement powers, but the bureau’s role as an INTERPOL contact point does not independently confer arrest powers beyond those granted by national law.
For the officer at a checkpoint, that coordination can resolve practical uncertainties about whether the notice remains active, whom to contact, and which domestic procedure to follow before authorizing any continued detention.
A Database Match Must Be Verified
An apparent match can begin with a name, date of birth, passport number, photograph, or biometric comparison, but officials must determine whether the person encountered is actually the individual identified in the foreign wanted-person record.
Similar names, different transliterations, outdated photographs, incomplete biographical details, and identity theft can create uncertainty, making corroboration important before authorities impose prolonged restrictions upon someone whose connection to the notice remains disputed.
Officers may compare several reliable identifiers and seek additional information through official channels, while the traveler or counsel may provide authentic records demonstrating that an apparent match concerns another person or inaccurate government data.
Confirming identity still does not answer every legal question, because a correct match establishes who the person is while the applicable statute, warrant, or judicial order determines what authorized officials may do next.
The United States Requires More Than the Notice Alone
Justice Department guidance explains that the United States does not regard a foreign Red Notice alone as a sufficient basis for arrest, so an American extradition arrest requires additional authority recognized under domestic law.
In a conventional incoming extradition case, the foreign request moves through the appropriate governmental channels, and prosecutors may seek a domestic arrest warrant supported by the information required for the American extradition process.
American officers may also encounter someone independently subject to a United States criminal warrant or immigration enforcement action, but they must distinguish those grounds from claiming authority to arrest solely because a Red Notice exists.
The example illustrates the central point without establishing a universal procedure, because another country may give the notice different legal effect or permit urgent provisional arrest under legislation with different requirements and safeguards.
Urgent Arrest and Continued Detention Are Separate Decisions
Provisional arrest addresses the possibility that a wanted person will leave before a full extradition request can arrive, allowing authorized officials to preserve the opportunity for proceedings where national law and treaty arrangements permit that measure.
An urgent initial arrest does not create unlimited authority to keep the person in custody, because subsequent detention may require judicial review, supporting materials, compliance with statutory deadlines, and an ongoing legal basis for restraint.
The requesting country may need to transmit its formal extradition package within a specified period, with the consequences of delay determined by the applicable treaty and the law of the country holding the person.
If the required materials do not arrive, release from provisional detention may become necessary, although that release does not necessarily cancel the foreign warrant or prevent later proceedings where renewed action is legally permitted.
Arrest Does Not Decide Extradition
Amicus International Consulting’s material on international extradition procedures addresses the broader process that can follow location and arrest, involving authorities whose responsibility extends beyond identifying a wanted person or maintaining temporary custody during an urgent encounter.
Formal extradition review may consider treaty coverage, identity, the criminal character of the alleged conduct, required evidence, limitation periods, nationality restrictions, and objections recognized under the requested country’s legislation and international obligations.
In many jurisdictions, courts and executive officials share responsibility for different stages of the surrender decision, meaning a favorable judicial determination may still be followed by a ministerial decision or additional legal review.
Arresting officers generally lack authority to resolve all those issues themselves, and successful apprehension should not be reported as automatically establishing guilt or guaranteeing return to the requesting country.
The Watson Case Shows the Separation of Powers
Paul Watson’s detention in Greenland in July 2024, followed by Denmark’s refusal to extradite him to Japan in December, illustrates how physical arrest, continued custody, and the final response to a foreign request can involve separate national decisions.
According to Reuters reporting on Watson’s release, Danish authorities rejected Japan’s extradition request after considering factors including the age of the case and uncertainty about credit for the time he had spent detained in Greenland.
That sequence shows why identifying the institution responsible for each stage matters: officers can lawfully apprehend someone to consider a foreign request without controlling whether the government ultimately agrees to surrender that person.
One case’s outcome does not determine another country’s response to a different notice, but it illustrates the distinction between operational police action and the later legal decision on extradition.
Immigration Officers May Exercise Separate Authority
A person named in a Red Notice may also face immigration questions about admission, visa eligibility, residence, or removal, and officials may consider the underlying information where national immigration law permits.
Any immigration detention requires its own legal basis, which should be identified separately from provisional arrest for extradition even when the same notice brought the person to the attention of both police and immigration authorities.
Refusal of entry or removal can have serious consequences, but those measures address different legal questions from a formal foreign request to surrender someone for prosecution or enforcement of a criminal sentence.
Counsel assessing an encounter must therefore determine whether officials are using immigration law, criminal arrest powers, or extradition procedures, because the available objections, reviewing authorities, deadlines, and safeguards may differ substantially across these categories.
Foreign Investigators Cannot Rely on Their Own Badge Alone
Investigators from the requesting country may assist foreign partners with identification, evidence, witness information, or operational planning, but their domestic credentials do not automatically authorize them to exercise coercive powers in another jurisdiction.
Participation in a joint investigation or coordinated operation depends on relevant agreements and local law, with the host country’s authorities ordinarily controlling arrest and custody within its territory.
Once surrender is lawfully approved, officers from the requesting country may receive the person through an authorized handover and escort arrangement, which is legally distinct from entering the country and independently executing the original warrant.
A press release describing international cooperation should therefore identify who located the person, who made the arrest, who authorized detention, and who approved transfer, rather than attributing all four functions to one organization.
The Person Can Challenge the Basis for Detention
A person arrested following a Red Notice match may seek available legal assistance and challenge identity, the asserted arrest power, missing documentation, or continued detention through the procedures recognized by the country controlling custody.
Challenges to INTERPOL data operate separately from proceedings concerning the original national warrant or the arresting country’s extradition process, so success in one forum does not automatically resolve every outstanding legal issue elsewhere.
For example, deleting an international notice does not necessarily cancel a domestic warrant, and a court order releasing someone from one form of detention requires careful examination of any other lawful basis officials claim for holding them.
The practical legal task is to identify the actual instrument supporting custody and the authority responsible for reviewing it, because the phrase “INTERPOL arrest” alone does not provide enough information to assess whether detention is lawful.
Authority Remains With the Relevant Jurisdiction
When a Red Notice leads to an encounter, police and other authorized officers perform the operational work, prosecutors or designated authorities pursue necessary applications, and courts review matters assigned to them under the applicable legal system.
INTERPOL supports that process through international communication, information services, and specialist assistance, while the requesting country preserves responsibility for its criminal case and the receiving jurisdiction controls the coercive measures taken on its territory.
The answer to who can arrest therefore depends upon the officer’s legally granted powers and the basis for the particular action, rather than the international visibility of the notice or the seriousness of its allegations.
For anyone examining an actual case, the essential documents are the underlying warrant, the authority invoked for arrest, any judicial detention order, and the applicable extradition or immigration provisions governing what the responsible officials can do next.
