BANGKOK, Thailand: Law enforcement authorities Tuesday (May 21st) seized about 4.5 million methamphetamine pills and 60kg of crystal methamphetamine worth around 1.5 billion baht ($50.23m) from a condo in Bangkok's Bung Kum district, according to local media.

Acting on a tip, police raided two rooms of Peera Phokaew Mansion in Soi Phokaew and found the drugs hidden in a wardrobe, The Bangkok Post reported, quoting Office of the Narcotics Control Board (ONCB) secretary-general Pol Gen Pongsapat Pongcharoen.

Three suspects -- Suthichai Kama, 22, Sing Kaewpu, 20, and a 16-year-old boy – were arrested during raid.

Pol Gen Pongsapat said the suspects were hired to watch over the drugs, which he said had been brought to Bangkok from Chiang Rai by the Wa drug network.

On Monday, police launched a crackdown on a major drug trafficking gang in Bangkok, detaining one suspect, and seizing assets worth more than 50m baht ($1.68m).

Pongsapat said police arrested Thanyaporn Khanankhaeng, 36, who claimed not to know the whereabouts of her husband and alleged gang leader Kosin Chuchai, 31. Police continue to search for him and 10 other accomplices.
