AN unemployed man who abducted his lover's young son to force her to pay $15,000 was sentenced in the High Court yesterday to 61/2 years in jail. The penalty was handed down by Deputy Judge Bokhary after a jury found Leung Chi-wah guilty of the forcible detention of three-year-old Nguyen Ngoc Hung with intent to procure a ransom. Passing sentence, the judge stressed that kidnapping was a serious offence and, in this case, had caused great distress to the little boy's family. However, he accepted the child did not appear to have been ill treated. Leung, 30, had denied the offence, claiming that the money was owed to him by his lover, Jenny Pham Thi Hong Cham, a karaoke club worker. Prosecutor Corinne Remedios had called evidence that Ms Pham, who had separated from her husband, came to know Leung at the end of last year and went to live with him in a Tai Kok Tsui flat. She had collected the boy, who lived with someone else, to spend the Lunar New Year with her when Leung asked her for money, and she refused. Leung then took the boy to a friend's flat in Tsing Yi and kept him there for four days, during which time he telephoned Ms Pham and demanded a ransom of $20,000, which he later reduced to $15,000. He was arrested when he went to collect the money. Leung, defended by Robin Walters, denied kidnapping the boy, contending he was looking after him for a few days with his mother's consent. He maintained the fact that the child, who called him 'papa', was staying with him had nothing to do with the demand for money which was owed to him by Ms Pham. After the conviction, Mr Walters, in mitigation, said the boy was not harmed in any way. either psychologically or physically, and probably did not even know he had been kidnapped.
