A man who dreamed of a career in the police force was caught impersonating an officer when he offered to assist a policeman twice in two days. Former film extra Lo Chak-cheung, 25, was arrested with a handcuff pouch and fake police warrant card on May 10, Eastern Court heard yesterday. Two days before, Lo had approached a police officer who was body-searching a man in Lockhart Road. Lo claimed to be attached to the Hong Kong Island Regional Crime Unit and asked the officer if he needed help. The same officer recognised Lo when he again offered to help during a street raid on May 10 outside Causeway Bay Plaza. Yesterday Lo admitted impersonating an officer and using a false instrument. In mitigation, Lo's lawyer said his client had fantasies about becoming a policeman since his father forbade him from joining the force. Lo, who has two previous convictions for impersonating an officer, has a collection of police T-shirts and badges, the court heard. Magistrate Abu Bakar bin Wahab adjourned sentencing to September 26 pending background and psychological reports.
