A police sergeant was arrested and charged for allegedly giving advice to four people in relation to their suspected unlawful activities, the anti-graft watchdog said yesterday. Edward Fung Hin-wah, 47, faces one count of misconduct in public office, the Independent Commission Against Corruption said. Decoration worker Lau Kim-hung, 39, and Chu An-bun, 39 and unemployed, were charged with conspiracy to offer advantages to a public servant. The defendants, who are on ICAC bail, will appear in Kowloon City Court on Tuesday for mention. The first charge alleges Fung committed wilful misconduct by giving advice in relation to unlawful activities to Lau, Chu and two others in June last year. Lau and Chu are accused of offering advantages to Fung for protection and prior warning of police action. The advantages involved shares in a private club that was to be set up by two other people. Under the Prevention of Bribery Ordinance, the maximum penalties for offering advantages to a public servant are a HK$500,000 fine and seven year's jail. The anti-graft body said about 30 officials, mostly civil servants, had been charged with misconduct in public office since 2000, with 18 convicted. In a separate case revealed in the course of the ICAC investigation, Lau and Chu were charged jointly with trafficking in dangerous drugs.
