A Chubb security guard is in a critical condition after being shot in the chest during a routine cash pick-up in Sydney's CBD this morning.
Police said four men in a silver Audi stopped a armoured security van outside a hotel near the corner of Market and Sussex streets about 5.50am.
The men, who were believed to be wearing balaclavas, approached the security guards in the van and demanded access to it, police said.
There was a fight and it is believed one of the guards was shot in the chest at close range, critically injuring him.
The guards were believed to have been making a cash drop at a food court.
Police said the alleged thieves left in the Audi and were last seen heading south on Sussex Street.
It is believed the men did not leave with any cash.
A gym employee and a garbage truck worker were understood to have witnessed the shooting.
The injured guard was taken to Royal Prince Alfred Hospital.
The man's colleagues are still at the site of the shooting.
A witness said he heard the sound of a tyre blow but did not think anything of it.
He said police arrived a short time later and an ambulance drove off after that.
Peak-hour traffic chaos is expected, with Sussex Street closed between Market and Druitt streets.
Police warned the four men were dangerous and should not to be approached.
