A 17-year-old was yesterday convicted of raping a former primary schoolmate in a Sha Tin Japanese restaurant - which was filmed and later put on the internet. Two other teenagers accused of helping him commit the rape were found not guilty. The jury at the Court of First Instance found Ho Ka-kit guilty of rape. Student Ma Ho-kan, 16, and assistant shop manager Kewell Li Hau-chung, 19, both charged with aiding and abetting the rape, were found not guilty. Ho-kan, who allegedly instructed the girl to tell police that the sex was consensual, was also found not guilty on the charge of perverting the course of justice. All three pleaded not guilty. The defendants appeared calm upon hearing the verdict, and Mr Ma and Mr Li ran out of the building afterwards. Ho will be sentenced on September 7, pending a report on the impact of the rape on the girl, and a psychologist's report on him ordered by Judge Judianna Barnes Wai-ling. The girl, 16 at the time of the rape and identified only as Miss X, had testified that Ho forced her into a manager's office in the restaurant in Lek Yuen Shopping Centre in April or May last year - she could not remember the exact date. There, he raped her while Mr Li filmed the assault on his mobile phone. She said she screamed and tried to call the police on the phone, but the trio stopped her. She had testified from behind a screen during the trial. She said she had kept quiet about the rape because she had feared that, if she did not, the video would be circulated online. But in September last year, the footage surfaced on the internet. Restaurant staff reported the attack to the police, who arrested the three. Ho told the court he had met Miss X when they both were in Primary Four at a Tai Po school, and that she had admitted liking him during their Primary Six graduation. But he did not respond and the two separated. They did not meet again until October 2007 when he, Mr Ma and the girl began to work together part-time at the Japanese fast-food restaurant, he said. Ho said she had agreed to have sex with him. He said the four were 'playing around' that night when he proposed that they have sex - the first and only time they did so.
