Police seized nearly 1 million methamphetamine tablets worth about $12.7 million and arrested three suspects Sunday in Thailand, press reports said.

The drug bust was made at a checkpoint in Chiang Rai, a province in northern Thailand, after two suspicious automobiles were stopped, Lt. Gen. Priewpan Damapong told the Bangkok Post.

Officers found 958,000 methamphetamine tablets hidden in the roof of one of the vehicles.

The suspects - three men and a woman - told officers they had been paid about $30,000 by Thamnoon Asavakul, a suspected drug trafficker, to transport the illegal stimulants to Samut Prakan province, which borders Bangkok.

The so-called Golden Triangle formed by Myanmar, Laos and Thailand is one of the world's main drug trafficking centers, with smugglers moving methamphetamine and opium through the region. EFE
