A man sentenced to six years' jail for attempting to rape a glue-sniffing teenage runaway was freed by the Court of Appeal yesterday. Cheung Yuen-chung, 21, had been accused of taking part in the attempted gang rape of the 13-year-old girl at a container yard on June 8, 1995. The girl had claimed she was held down by Mr Cheung and two youths. But during the trial the confused victim repeatedly told the jury different versions about the night she spent sniffing glue in the Lok Ma Chau container yard. Mr Justice Henry Litton said inconsistencies in the teenager's evidence against Mr Cheung were ignored by the jury when it sentenced him on January 30 last year. The Court of Appeal believed the discrepancies in the runaway's evidence left enough doubt in their minds to allow Mr Cheung's appeal. The girl had claimed she was held down on a sofa and stripped, and that Mr Cheung had tried to rape her. But at other times she told the court Mr Cheung had left to take a shower when the attempted rape occurred. Mr Cheung and Cheung Man-tsan, 16, who was also sentenced to six years in prison for his part in the crime, claimed the police had brutally extracted confessions. The trial judge, Mr Justice Michael Wong Kin-chow, had said: 'Police stations are not five-star hotels,' and 'a little rough handling' might occur. Cheung Man-tsan failed to have his conviction overturned yesterday, but the Court of Appeal said it would hear submissions in six weeks to shorten his sentence. The third youth, who cannot be named because he is aged under 14, was sentenced to a training centre. The appeal was heard before Mr Justice Litton, Mr Justice Kemal Bokhary and Mr Justice Raymond Sears.
