A schoolgirl was spared prolonged torture, humiliation and serious injuries after her best friend made an escape and reported the incident to police after watching her being stripped, beaten and forced to snort washing powder at a Tin Shui Wai flat, a court heard yesterday. The victim, now 17, whose name the court ordered could not be revealed, went with three friends to the home of Chung Ka-lun, 24, and his co-accused Chau Chun-tat, 34, for a party on September 26 last year. Chung at first denied one count of indecent assault, and one count each of false imprisonment and assault occasioning actual bodily harm. He changed his plea to guilty in the middle of the first day of the trial yesterday in the District Court. Chau, who was accused of a count of indecent assault, as well as one count each of false imprisonment and assault occasioning actual bodily harm, maintained his not guilty plea. The party spun out of control when Chung burst into rage and accused the victim of lying. The schoolgirl's friend, who was only identified as Ms Lam, said yesterday she was frightened something awful would happen to her friend. Ms Lam said Chau and Chung repeatedly beat and burned the girl and threatened she would not be able to survive the Mid-Autumn Festival, which was in October last year. 'Her chest swelled and she was in pain, we wanted to leave the flat but [Chung] said no one could leave until we got ourselves involved by beating her,' she said. 'They thought the whole thing was a game, but I didn't feel like it was fun.' The victim also told Deputy Judge Patrick Li Hon-leung via close-circuit television yesterday: '[Chung] and [Chau] punched me on my chest and limbs for 15 minutes, they hit my leg with crutches and [Chung] put an intercom cord around my neck and pulled ... I thought I was dead,' the victim said. Ms Lam said Chung stuck a couple of burning incense sticks on the girl's tongue. Later she was made to snort washing powder like heroin and was also told to stage sex scenes in front of her friends, the court heard. The victim was stripped naked by the two defendants, who claimed that they wanted to 'inspect her wounds'. Ms Lam filed a report to the police after escaping. Police stormed the flat in the early morning of September 27 and arrested the two defendants. 'I was only allowed to leave after leaving my ID card number and home address,' she said. The trial continues today.
