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 were arrested Tuesday night at the club in northwestern Siem Reap province. Sun Bunthong, chief of Siem Reap's anti-human trafficking police, said the men forced the 18-year-old to drink beer until she was intoxicated, then asked other women to leave the room. "After girls who were not drunk were out of the room, they locked the door and one of them started raping her," he said.
