Three Vietnamese and one Chinese national were charged with drug trafficking and dealing by the Svay Rieng Provincial Court yesterday after police seized from them a total of 45 small packages of methamphetamine, police said yesterday.

Chinese national Chang Wei and Vietnamese nationals Nguyen Ty Heng, Le Te Rac and Minh Nguc were arrested following three related raids on Friday and Saturday in Svay Rieng province’s Bavet town, said provincial anti-drug police chief Kan Ken.

Officers discovered several packages of meth in the room of the Malay guesthouse where Chang was staying, and the raid guided them to their later arrests of Nguyen and Le at the Las Vegas Casino and finally Minh at the Phka Chhouk guesthouse, where they discovered more meth, Ken said.

The raids came after a police investigation of drug dealing in the casino, he added.

Police also seized a scale and various drug paraphernalia.
