A soft-toy salesman accused of kidnapping and murdering his lover's four-year-old son said yesterday that the woman's court testimony was false. Lam Shing-tak, 31, told the Court of First Instance he was not particularly attached to Ng Yu-ping, 32, and had only allowed her to live with him because she had nowhere to go after she split with her husband, Law Tai-yau, 34. Lam, who has pleaded not guilty to kidnapping and murdering the boy, denied prosecutor Frederic Whitehouse's allegation that he wanted Law Shiu-wai's mother 'to the point of obsession and found Shiu-wai's presence an obstacle'. He also denied stealing Ms Ng's travel documents in a bid to prevent her from moving out of his flat. 'After she moved out, you bought her a bed, bought her flowers, bought her a mobile telephone, and you still maintain you were not attached to her?' Mr Whitehouse asked the defendant. Lam replied: 'Most of what Ng Yu-ping said in her evidence is absolutely wrong. I was only helping a friend in need - you would have done the same.' Ng has testified that Lam did not like her son and had asked her not to see him again. Shiu-wai's body was found bound and gagged, floating in Gin Drinkers Bay, near Tsing Yi, by a fisherman on July 3, 1999, three days after he was kidnapped outside a restaurant in Aberdeen while his father was buying take-away food. Mobile phone records established Lam in the Ap Lei Chau area, close to Aberdeen, around the time of the abduction and in Tsing Yi later that night, the court heard. Lam has admitted he was in the vicinity, but denies he had any encounters with Shiu-wai. But Mr Whitehouse accused Lam of changing his story, originally telling police he was in Wan Chai. Lam replied only that his police statement was unsigned and that he had not been cautioned. The trial continues before Mr Justice Colin Jackson today.
