A Japanese-language tutor was convicted in the District Court yesterday of pressuring a 14-year-old student into having sex with him more than 10 times over three months. Gary Siu Cheuk-ming, 27, a former secondary-school teacher, was found guilty of indecent assault, two charges of procurement by threat to perform an unlawful sexual act, unlawful sexual intercourse with a girl under the age of 16 and indecent conduct towards a child under 16. Sentencing was adjourned to July 27, pending reports from a psychologist and psychiatrist on the defendant and a victim impact report. Court documents said the girl, now 16, was a student in one of Siu's Japanese classes held at a community centre in Tseung Kwan O during the summer of 2006. Siu asked her whether she was interested in modelling for an agency he claimed to be involved with. In July 2007, Siu called her to a meeting at a hostel in Kwun Tong where he asked her to take off her clothes for measurements. The girl was molested at the meeting. Later, Siu had asked the girl twice to hostels where he molested her under the pretext of taking measurements. He also filmed her naked. In September the same year, Siu told the girl that she had missed a photo shoot - which would cost the agency up to HK$40,000 - and threatened to distribute the video unless she went out with him once a week. The girl told the court that she had sex with Siu 10 to 20 times until November 2007, when she told a teacher what had happened and the case was reported to the police. Siu had pleaded not guilty before Deputy Judge Li Wai-chi. Mr Li said the conviction was largely based on the girl's evidence. The court also heard Siu had been jailed for five months last August for indecent assault on another student of his Japanese-language classes. Mr Li said this would serve as an aggravating factor in sentencing. The Law Reform Commission launched a consultation last July on a registry of sex offenders. But only an interim measure under which employers in child-related services can obtain records of prospective employees has been proposed. The checks would not be compulsory. Priscilla Lui Tsang Sun-kai, director of child welfare group Against Child Abuse, urged the government to speed up efforts to protect children from repeat child molesters.
