Preah Vihear provincial and Choam Ksan district military police on Friday raided the house of a drug dealer, arresting four suspects and seizing 94 bags of crystal methamphetamine.
Choam Ksan district military police chief Pich Sophy said the four, including one woman, were arrested on drug-related charges.
“We found 94 small bags of crystal meth, one AK-47, one M16 and one homemade rifle,” he said.
Mr Sophy said the suspects did not try to fight back and surrendered to officers, adding that the raid came after a tip-off from informants.
The suspects were sent to Preah Vihear provincial military police headquarters, he said.
Provincial court spokesman Phy Sithorng identified the woman as Muy Sophorn and the three men as Koun Ley, Ret and Chhin Veasna.
The three men all tested positive for drug use.
Ms Sithorng said that Ms Sophorn was charged with dealing drugs, while Mr Ley and Mr Ret were charged with possession and drug use, and Mr Veasna was charged only with using drugs.
Mr Veasna was released but the others have been detained and face between two and five years in prison.
