First day on the job nerves caused a Protective Services Officer to accidentally fire a gun inside Victoria Police’s headquarters in Melbourne.

Assistant Commissioner Chris O’Neill said the officer incorrectly removed a name identification tag on the weapon which caused it to fire inside the police armoury.

‘‘The PSO on his first day, obviously with some nerves as we all would be on our first day, has failed to remove this ID tag, which is only on it until the firearm issued, so it’s one of those things when you obviously only do it once,’’ Assistant Commissioner O’Neill said.

‘‘He’s loaded the firearm in the correct manner placed it in his holster ... [but] upon removing that name tag the trigger has been pulled and the firearm has been discharged.’’
