The boyfriend of a transsexual prostitute has been convicted of trying to solicit $1,000 from a man in return for giving favourable evidence in a court case. The transsexual, Fay Cheung Montana, 26, denied attempting to pervert the course of justice and was cleared after the Crown did not proceed against her in the District Court yesterday. But her boyfriend Ng Sai-keung, 28, admitted the charge. Prosecutor Selwyn Au said the pair had been potential witnesses in a case involving jobless Wong Yuk-lun. Wong, 19, was eventually bound over after denying charges of threatening the couple with a knife and threatening to set their house on fire. Before the trial in March, Cheung allegedly rang Wong to ask for $1,000 in exchange for giving false evidence in his favour. Wong reported the alleged bribe attempt to his solicitor. On the morning of March 12, police laid a trap to catch Ng after he received $1,000 from Wong, Mr Au said. Cheung, who had a sex-change operation in 1994, is now serving a three-month jail sentence for soliciting after pleading guilty to offering sexual services to an undercover policeman. Judge Wong Hing-chun yesterday adjourned Ng's sentencing until October 22 for background reports.
