A sex offender who tried to rape a teenage girl received a two-year reduction in his jail term yesterday, after the Court of Appeal heard the 13-year-old victim spent a second night in his company. Cheung Man-tsan, 19, and two other youths had tried to rape the teenage runaway on a sofa in a deserted container, the court heard. Mr Justice Michael Wong Kin-chow sentenced Cheung and Cheung Yuen-chung, 21, to six years' jail for the attempted rape on January 30, 1996. A 14-year-old youth, who cannot be named, was sent to a training centre. The girl met the trio on June 8 in a Lok Ma Chau container terminal after she fled her home because of a quarrel with her mother. The group had sniffed paint thinner. The girl said during the night she was held down on the sofa as the group tried to rape her. Mr Justice Michael Stuart-Moore said in 'assessing the gravity of the evidence', the court considered that 'the victim spent the remainder of the night on the ground floor of the container, which was occupied by the accused and others'. 'When the victim got up, she went out shopping in Fanling with her female friend. She returned and spent the second night in the container.' A January 18 Court of Appeal hearing freed Cheung Yuen-chung after finding inconsistencies in the girl's story. Yesterday's hearing before Mr Justice Henry Litton, Mr Justice Kemal Bokhary and Mr Justice Stuart-Moore ruled Cheung Man-tsan's six-year sentence 'manifestly excessive' and reduced the term to 41/2 years.
