CHIANG RAI, Thailand – Authorities seized more than 4.2 million methamphetamine pills in two separate busts in Chiang Rai late Thursday and early Friday (March 2nd).

Police recovered 4,080,000 pills after chasing a pickup truck and two motorcycles that failed to stop at a border checkpoint Thursday. Authorities found 34 packs in the back of the truck with 60 bags of pills after the vehicles had been abandoned by the drivers and passengers. Pol Col Surachet Topunyanont, the acting Chiang Rai police chief, said the drugs were believed to have been smuggled from Burma, according to The Bangkok Post.

Deputy Prime Minister Chalerm Yubamrung said two suspects had been captured and an arrest warrant was issued for two others still on the run.

In a separate incident in Chiang Rai, police arrested three men found to be in possession of 200,000 pills Friday. Acting off a tip, Mae Sai police tracked a white van from the border. The driver and a passenger told police they were paid 60,000 baht ($1,960) to deliver the drugs from Burma that were destined for Bangkok.
