Border patrol police arrested a Taiwanese national and a Thai man in a raid on a warehouse in Chon Buri province on Sunday, Border Patrol Police deputy commissioner Prapan Chan-em told a press conference on Monday.
Pol Maj Gen Prapan identified the Taiwanese man as Chi J San, 64, and the Thai as Supornchai Chukaew, 44.
BPP Compay 244 on Aug 23 learned that a large quantity of marijuana had been smuggled across the border from Bolikhamxay province of Laos to Muang district of Bung Kan province. The marijuana was later transported to a warehouse in Chon Buri, to be smuggled to Australia, he said.
The information led to the raid on the warehouse in tambon Bo Kwang Thong in Chon Buri's Bo Thong district on Sunday.
The BPP seized about 3 tonnes of marijuana. The drug was sealed in packages, to be placed in boxes with labels declaring they contained rubber gloves for medical use.
The Taiwanese man said he had opened a company in Chon Buri in 2007 to export rubber gloves as a front for the drug trade.
He ordered the marijuana from Laos, to be delivered-on to a third country. Mr Supornchai, the Thai suspect, supervised the warehouse.
The two were charged with having illicit drugs in possession with intent to sell.
The police investigation was continuing.
