Customs officers seized 779 pieces of ivory weighing 1,323 kilograms (2,916 pounds) in a shipping container that arrived at Hong Kong's port from Kenya after passing through Malaysia.
The officers discovered the ivory after X-raying the container, which was declared to be carrying architectural stones. Forty sacks holding the ivory were found inside five wooden crates, hidden under rocks.
The investigation is still continuing. No one has been arrested.
