Customs officers have seized 503kg of ivory tusks and 556kg of turtleshell stashed in a container from Tanzania. Officers believe the consignment could have been sold for $700,000 in an underground market in the city. The haul was discovered when no one arrived to pick up the container and customs officers opened it for inspection at their cargo examination compound in Kwai Chung on Monday. Inside the container were 70 bags of tusks, 51 bags of turtleshell and 175 bags of dried fish maws, officers said. The container was shipped into Hong Kong on May 5 from Tanzania via Singapore. Yesterday, the Customs and Excise Department said no arrests had been made and investigations into the haul were continuing. The seized goods have been handed over to the Agriculture, Fisheries and Conservation Department. Under the Import and Export Ordinance, any person found guilty of 'importing unmanifested cargo' is liable to a maximum fine of $2 million and imprisonment for seven years. Under the Animals and Plants (Protection of Endangered Species) Ordinance, any person found guilty of trading in endangered species for commercial purposes is liable to a maximum fine of $5 million and imprisonment for two years.
