Police are concerned by the calm demeanour of a man who robbed a North Shore bank at gunpoint today yet made no attempt to disguise his identity.
A CCTV image of the man, showing little emotion as he threatened staff at the Mairangi Bay ASB, was released by police this afternoon.
Detective Senior Sergeant Stan Brown said the man walked into the bank about 11am and waited patiently in line until it was his turn.
"It turned a bit nasty when he got to the counter and pulled a gun, which looked similar to a Glock pistol, and demanded money," he said.
"Very calculated would be one way to describe it."
The teller handed over an undisclosed amount of cash and the man walked out of the bank. He remained at large this evening.
Mr Brown said it was unusual for a robber to make no attempt to cover their face.
"It does happens from time to time but certainly there's a few aspects that we're a bit concerned about it - he was very calm but without making any attempt to disguise his face knowing that every bank has CCTV."
Mr Brown did not wish to speculate about what this said about the man's state of mind or intent.
"We have our guesses but until we talk to the person involved we can't really say."
He urged members of the public who recognised the man to contact police immediately.
"It's a pretty good picture so I hope we get the phone call in the next few hours."
