The trial of two men accused of attempting to pay off a police officer in return for protection will continue despite potentially prejudicial evidence against one of them being admitted into proceedings. Deputy District Court Judge Josiah Lam Wai-kuen dismissed an application to stay proceedings against Lau Kim-hung, 39, who pleaded not guilty to one count of conspiring to offer an advantage to former police sergeant Edward Fung Hin-wah. Barrister Bruce Tse had asked the judge to order a retrial after an undercover Independent Commission Against Corruption investigator told the court the graft-busters had knowledge Lau was involved in drug dealing activities separate to the crimes he has been charged with. Chu An-bun, also 39, has also pleaded not guilty to conspiring to offer an advantage. Fung has pleaded not guilty to one count of misconduct in public office. In the application, Mr Tse alleged the ICAC officer, whose alias was 'Ah Chun', had revealed information in his testimony that was prejudicial to his client. Mr Tse also alleged the fact the prosecution had revealed Lau was currently serving a prison sentence would also prejudice his case. However, the judge dismissed the application, saying that he had immediately disregarded the prejudicial elements of Ah Chun's evidence. The charges against Lau and Chu arose from a 2007 ICAC investigation into allegations that a police officer was offering protection to a drug dealer. Chu and Lau had introduced Ah Chun to Fung, after the agent claimed his boss planned to set up a private club to provide drugs and prostitutes and was interested in protection. Fung is alleged to have given advice on how to run the club. The hearing continues on Monday.
