A man accused of trying to enter a Christchurch Work and Income office with a gun and letting off a shot outside, also threatened to kill Winz workers, police are now alleging.
Mitchell Shane Moulton, 32, allegedly went to the Linwood office just before 8.45am on October 6.
He allegedly threatened security guards before fleeing the scene.
The police armed offenders squad was called out and he was later tracked down by police, officers said at the time.
Last month, he appeared at Christchurch District Court charged with possession of a firearm, letting off a shot, and possession of cannabis.
