The thief stole the bag of money while two accomplices - one of whom was wearing a black face mask - distracted the Brink's employee by asking him for directions.

Brink's is a private security company which offers cash transportation services.

The security worker was about to make a money drop at a Chase Bank branch in Sunset Park, Brooklyn, when he was approached by the robbers at about 1pm on 6 January.

In images taken from a surveillance camera outside the bank, a man can be seen crossing the street with what appears to be a bag of cash in his hands.

Police released photos of the men on Saturday and asked for the public's helping finding them.

A Brink's spokesperson said the company is working with law enforcement.
