Four Vietnamese nationals were arrested on Monday over their suspected involvement in the murder of a fellow Vietnamese man at the New World Casino in Svay Rieng province’s Bavet town the day before, deputy district penal police chief Kav Horn said yesterday.

Horn confirmed the arrests and that the victim was killed on Sunday, but declined to offer any more details other than that the investigation was being led by the provincial prosecutor and that “the four suspects have now been sent to provincial police”.

Provincial prosecutor Kong Chan Khemrith also declined to comment on the details of the case. “We just suspect them because they were in the next room,” he said. “So now we cannot say if they are guilty or not guilty; now we are checking the [security] camera. After we finish checking the camera, we will know for sure whether to send them to the court or release them.”
