Customs officials seized a half ton of African ivory hidden in crates at a wharehouse at Suvarnabhumi Airport in Bangkok last Friday.
A total of 158 pieces of ivory from the tusks of an estimated 50 elephants worth THB22 million was confiscated, MCOT reported. The ivory weighed 456 kilograms.
Officials made the raid based upon a tipoff and checked the crates which were labeled as handicrafts and had entered Thailand as air-freight from Kenya.
Ivory trading is illegal under the Convention of International Trade in Endangered Species (CITES), and the Wild Animal Reservation and Protection Act, among other laws.
Bangkok is one the biggest international hubs of the illegal wildlife trade.
Customs officials also seized 11 pythons and a baby monkey from a Kuwaiti woman trying to board a flight out of Suvarnabhumi last week.
