Man suspected of five armed robberies at service stations in Melbourne's northwest POLICE believe the same man may be behind five armed robberies in Melbourne's northwest in the past fortnight. In each robbery a man armed with a knife has held up service stations in Sunbury, Woodend and Sydenham, escaping with a small amount of cash each time. All robberies occurred late at night or early in the morning. One service station, on Gap Rd in Sunbury, was struck twice in two weeks. Fawkner Embona Taskforce detectives have released an image captured on CCTV of a man they would like to speak to in relation to the incidents. He is described as being Caucasian, with a solid build, about 180cm tall, and was wearing a hooded top during the robberies.
