An imposter posing as a police officer tried to 'arrest' a 24-year-old Dandenong man for attempted murder. The 24-year-old victim showed up at the Dandenong police station on Sunday afternoon still in handcuffs after the fake officer fled from his house in Hutton Street. The imposter allegedly turned up at the home of the victim and his mother and flashed a police badge before arresting the man for attempted murder. With his victim in handcuffs, the imposter then demanded the combination of a safe. Senior Constable Mark Higgins told radio station 3AW the victim's suspicions were immediately raised because the man was alone and was not wearing any police identification. "He had a feeling that something wasn't right...because he wasn't wearing a lanyard or police identification and was in plain clothes without a kit, so to speak," Constable Higgins said. The imposter ran off after the victim refused to give him the combination to the safe. The victim later went to his local police station, where firefighters were called to remove the handcuffs. The imposter is still at large. Anyone with information is asked to Crime Stoppers on 1800 333 000.
