Battambang provincial police arrested two men and two women accused of smuggling half a kilogram of crystal methamphetamine yesterday in Phnom Proek district.

Deputy provincial police chief Colonel Cheth Vanny said the group of four were arrested after a traffic stop revealed they were in possession of 500 grams of crystal methamphetamine, a rifle, a pistol and a cache of ammunition for the firearms.

He added that he was under the impression the group had committed acts of drug trafficking prior to the arrests.

Provincial court prosecutor Uy Samphear could not be reached for comment yesterday.
