A BUSINESSMAN was yesterday convicted of raping a mother of two after grabbing her outside a block of flats. Wong Wing-sun, 31, was caught in the act when an elderly insomniac was alerted by the victim's screams. After the verdict, Mr Justice Seagroatt took the rare step of asking for a psychiatric report on the woman before passing sentence. Although judges may ask for such reports on defendants, it is unusual for them to request such information on a victim. But Mr Justice Seagroatt said: 'I have not yet come across a rape case where there has not been significant psychological damage. It would be wrong for me to sentence without that information available to me.' During the High Court trial, the woman told how she was walking home at 3 am on May 2 when Wong grabbed her from behind. He punched her in the back and dragged her into Kui Wo House on the Tai Wo Estate. She told the jury: 'I cried out 'help!'. He hit me repeatedly in the back. I continued shouting and trying to resist. 'He took me to the staircase. He pulled my dress over my head and told me to put my hands on the staircase. I told him not to do it because I had a period. He raped me. I was crying.' The 36-year-old karaoke hostess said she was terrified during the ordeal. Chow Fu, in his 70s, told how he saw Wong having sex with the woman on the staircase after hearing her screams. Wong, the owner of a manufacturing company, was acquitted of a second count of attempted buggery. He denied both charges. Prosecutor Paul Madigan said the woman had refused offers of counselling. But Mr Justice Seagroatt said: 'This is often a reaction initially, then problems start to appear.'
