BANGKOK, May 8 (Xinhua) -- A haul of over 400 kilograms of crystal methamphetamine was seized by authorities in southern Thailand on Tuesday, said a police source.

The authorities found 14 fertilizer bags dumped on the side of a road in Khuan Kalong district of Satun province, about 985 kilometers south of Bangkok, containing 448 kilograms of crystal methamphetamine in plastic bags which were allegedly meant to be smuggled across the border into Malaysia, according to the source attached to the National Police headquarters in Bangkok.

Those crystal methamphetamine, allegedly produced in Myanmar territory, smuggled across the border into northern Thailand and trafficked down to southern Thailand, could sell for some 500 million baht (about 16 million U.S. dollars) in a blackmarket, a police officer, based in the southern province, was quoted as saying.

However, no suspected drug traffickers were arrested after they had apparently dumped the crystal meth from a pickup truck on the side of the road, just a few kilometers from a road checkpoint, and fled.

Satun is one of Thailand's southern provinces which share border with Malaysia.
