An unemployed man accused of the multiple rape of an Indonesian domestic helper threatened to send her family pictures of her naked if she told police what he had done, a Court of First Instance jury heard yesterday. Chan Ka-man, 35, also warned the 21-year-old not to think of escaping because he would tell police she was a thief, the court was told. He has pleaded not guilty to six charges of rape and three of indecent assault, between July 15 and September 16 last year at his flat in Lei Muk Shue estate, Tsuen Wan. Prosecutor Polly Wan said two of the offences happened while Chan's five-year-old son was in an adjoining room. Ms Wan told the jury the maid began working for the defendant and his wife on June 26 last year. She said the first sexual assault took place on July 15, when Chan asked the helper to massage him but instead insisted on massaging her. Despite her attempts to fight him off, he stripped and fondled her, Ms Wan said. Being new to Hong Kong, the helper did not know who to turn to for help and feared she might lose her job if she reported Chan, she said. Between July 15 and the end of August, Chan raped the maid six times while his wife was at work, the prosecutor said. Chan said he would sack her if she told anyone, Ms Wan said. Despite his threats, the helper went to the police after she was again assaulted on September 16. She gave officers a tissue drenched with Chan's semen as evidence, the prosecutor said. The case continues today before Mr Justice Peter Nguyen.
