Banteay Meanchey military police officials in Poipet city arrested a drug kingpin over the weekend, also detaining his wife and four accomplices.
Provincial military police commander Brigadier General Born Bin said forces had been investigating the suspects for several months and seized six kilograms of drugs in the raid.
The operation was led by deputy provincial military police commander Sar Bunsoeung, with cooperation from provincial court prosecutor Meas Champiseth.
The drug ringleader was identified as Ly Leang Kong, 35, and his wife as Vun Sopheap, 28, who were detained pending trial.
Police said they confiscated five kilograms of dried marijuana, 250 grams of methamphetamine, and 594 tablets of ecstasy from the suspects.
They also seized two firearms, almost 100 bullets, a scale, and a Lexus car.
“Mr Leang Kong was an old target of ours, who has been imprisoned three times before, but still dares to commit drug-related crimes,” said Brig Gen Bin.
The prosecutor Mr Champiseth said he pushed for the arrests. “Even though this crackdown will not stop all drug problems in the area, I hope that arresting ringleaders will make others scared of committing drugs crimes in the region,” he said.
