A MAN has been jailed for eight years for raping a 14-year-old girl who went missing from home. Mr Justice Saied said Chiu Wing-shing, 28, had shown no repentance and had tried to blame a boy. He said Chiu was described in reports as having a strong sex drive. ''He may have over-active hormones but as reports indicate, he is fully orientated and doesn't have any mental disease as such . . . it may be the root cause of his problem is his preference for young girls,'' he said. He sentenced Chiu to three years each for two counts of indecent assault, to run concurrently with the eight years. The judge said a gang of at least five young people was involved. Although no weapon was used, the girl was threatened twice on a hillside when Chiu said he would set his dogs on her, and again when he threatened to throw her from a roof. In mitigation, Mahinder Panesar said Chiu had epilepsy and suicidal tendencies and clearly ''was not all there''. He was immature and had been described as a juvenile delinquent. He deserved pity more than punishment and needed treatment, counsel said. The judge also sentenced Leung Wing-chiu, who is now 16 but was 141/2 at the time of the offence, to a training centre on one count of indecent assault. He accepted Leung was under the influence of Chiu. Leung's counsel, Tse Hon, had asked for a fine. The victim followed the youths because she was lonely and frightened after sleeping away from home in April 1991. She went with them to a hillside, thinking they were taking her home, but she was raped and indecently assaulted. She was later indecently assaulted again.
