Sydney CBD shooting targets Armaguard truck An Armaguard truck was held up outside Broadway Shopping Centre on Bay St in Glebe. WEARING black clothes and balaclavas to hide their faces, they looked like players in a movie hold-up scene. But after one of the masked men fired a bullet into a glass awning above the Armaguard truck they were attempting to rob, it became clear these men were not actors. Police said one of the hooded bandits struck one guard in the back of the head with his weapon while he was manning the cash-in-transit vehicle outside Broadway Shopping Centre about 8.15am yesterday. Witnesses in a cafe across the road watched in horror as the men pulled in front of the armoured van in a dark station wagon and demanded cash. "One had a shotgun, one had an AK-47 and one had a Glock," a witness said. One spectator pulled out his mobile phone to videotape the incident before screaming out "Call the police, call the police" as the bandits surrounded the van. "Don't let them see that you've got your phone," the man in the video said. Another witness, who identified herself as Lauren, said everyone ducked behind a counter when they heard a shot: "We heard a shot being fired ... a couple of people were a bit scared and some of us ducked under the counter." Police said the thieves fled the scene empty handed shortly after firing the bullet. Leichhardt Police commander Superintendent Michael O'Toole was unable to confirm the gun used in the brazen attack, but said it was a "long-arms weapon." He said it was concerning to see so many attacks on armoured vehicles in daylight: "Of course we are worried they will strike again. It's a concern for something like this to happen at any time of the day, but especially when there are so many people around. Police are also investigating the link between stolen high-performance cars being used in these hold-up scenarios. Mr O'Toole denied holding-up cash-in-transit vans was becoming more prevalent, despite recent carjackings of a Mercedes from Vaucluse and an Audi from Ultimo last week. NSW Premier Barry O'Farrell said the safety of security guards was an ongoing concern: "It's a challenge. We have criminals out there with access to guns who are able to gain great reward by trying to knock off one of these vans. Bay Street was closed to traffic between Parramatta Road and Francis Street for most of the morning.
