A US Consulate-General agent will go on trial next month for conspiring to defraud the Hong Kong office of the Drug Enforcement Administration. Samuel Wong Pui-hang, 40, an assistant supervisor in the maintenance division, yesterday pleaded not guilty in Eastern Court to a charge of conspiring to defraud and two charges of accepting an advantage. It was alleged he accepted the bribes from Chu Kin-kwok, 41, owner of Kin Kwok General Repairs Company, and that he placed the consulate's maintenance work orders with Chu. The court heard Chu offered Wong a total of $10,000 in 1990 and 1991 to place work orders with him. Chu, who pleaded guilty to two charges of offering advantage, denied a charge of conspiracy to defraud and a count of false accounting. Magistrate Patrick Li Hon-leung adjourned Chu's sentencing until October 24 and fixed Wong's trial date for November 2.
