A man threatened staff at a bank in Chesham before stealing cash and fleeing. 

The attacker went into Lloyds Bank in the High Street at around 3.20pm on Wednesday (October 19). 

He approached the counter and threatened workers with violence before stealing money and running away on foot. 

He fled in the direction of The Broadway. 

Police searching for the 'dangerous' robber have now released three CCTV images in the hope that someone might recognise him.

He is described as having light brown skin, of slim to medium build and between about 5ft 8ins and 5ft 10ins.

He was wearing a black jacket and black hooded top, and was carrying an orange carrier bag.

Fortunately, no-one was injured during the incident.

"If you have any information, no matter how insignificant you think it might be, please contact police as soon as possible. The easiest way to do this is by calling 101 or visiting your nearest police station.
