PHNOM PENH - Three South Korean men have been arrested after one of them was caught raping an intoxicated Cambodian woman in their private room at a karaoke club, police said Wednesday.

Authorities said the three men - two restaurant owners and a tourist guide - were arrested immediately Tuesday night at the club in northwestern Siem Reap province, home to the famed Angkor Wat temples.

Sun Bunthong, chief of Siem Reap's anti-human trafficking police, said the men forced an 18-year-old girl to drink beer until she was intoxicated, and then asked other women to leave the room so that one of the men could rape her.

"After girls who were not drunk were out of the room, they locked the door and one of them started raping her," he said.

The men - whose identities were not immediately provided - were arrested after karaoke club staff forced their way through the door and saw one of them raping the woman, Sun Bunthong told AFP by telephone.

The man faces a rape charge while the two other men face charges of being accomplices to the crime, he added.
