SHOTS have been fired during a robbery of cash-in-transit security guards on Sydney's northside early today.
Police say four guards were robbed in Mount St, North Sydney just before 7am (AEST).
Several shots were fired but no one was injured, police say.
Two of the three robbers were carrying firearms. They fled the scene in a red sedan.
Police are appealing for witnesses while a crime scene has been established and examined for clues.
A delivery man called Mick saw the robbery and said it all happened just metres from where he'd parked his own van.
He said the robbers wore balaclavas, big jackets and gloves.
They made off with about four or five boxes of cash from the armoured van, as well as a sports bag full of envelopes handed over by the security guards, he said.
