Police are investigating a street robbery in which a firearm was produced in Burwood last night. About 9.15pm (Friday 29 July 2011), four teenage boys were sitting on a fence on Gordon Street, Burwood, when they were approached by two men. One of the men assaulted one of the 17-year-old boys before producing a weapon, described as a black-coloured pistol. The men demanded the boys’ wallets and other personal items, which were handed over. The men were last seen driving away in a silver hatchback, possibly a Volkswagen. Police from Burwood Local Area Command were alerted to the incident and detectives commenced investigations into the incident.
