Chiang Rai: Police in Thailand have seized nearly two million methamphetamine pills in the country’s northern border. Three people, belonging to the ethnic minority Hmong, have been arrested in one of this year’s largest drug busts. Law enforcement apprehended the men after chasing two pickup trucks near the Thai-Myanmar border in Chiang Rai province on Thursday night. Twenty kilograms of meth and 1.97 million tablets of methamphetamine were found in one of the pickups. Bangkok is planning to ask for Interpol’s help in tracing the drugs’ producers in Myanmar. More than 15 million methamphetamine pills were smuggled through Thai’s northern borders in 2011.
