A CARETAKER'S bribery conviction was quashed in the High Court yesterday because a magistrate had not made it clear if he was influenced by the mention of previous bribery allegations against the defendant. Mr Justice Duffy questioned the introduction of previous bribery allegations against Fok Siu-wing, 55, during his trial before magistrate Hugh Sinclair. 'This is highly prejudicial and ought not to have appeared before the court,' Mr Justice Duffy said. 'The record is silent as to how the magistrate dealt with this.' Mr Fok was convicted of bribery between November 26 and November 30 last year after a tenant at the Yee Kuk West Street building where he worked was alleged to have given him $2,000 to ignore alterations on a door of the tenant's premises. It was alleged that Mr Fok tried to divide the money with other caretakers. When they refused to share his windfall, he returned the money to the tenant, Lee Tsai-kan, the court heard. During his trial it was mentioned that Mr Fok had previously been suspected of taking bribes. Mr Fok, who was convicted at North Kowloon Court on August 9, was fined $2,000 and ordered to pay $5,000 costs. 'The appellant had on previous occasions been warned as to his future conduct,' Mr Justice Duffy said. He said Mr Fok had suffered enough by losing his job.
