Detectives think shoppers may have seen a car they believe is linked to a robbery at a Post Office in East Bridgford, Nottinghamshire.

Two teenagers, one white and one black, entered the Post Office, in Main Street, at about 5pm on Thursday.

They demanded money and threatened staff with small knives before fleeing with the cash.

Although staff were shaken no one was injured.

Anyone who saw the offenders, or a light blue car that could be linked to the incident, should call police.

Detective Constable Chris Macdonald, of West Bridgford CID, said: "If you were in the Main Street area of East Bridgford around the time of the incident and saw anything or anyone suspicious please call us.

"We are particularly keen to speak to anyone who may have seen a small blue car in the area. Were you on your way from home around that time?

Can you remember anything unusual in the area?"

The offenders are thought to be aged 17 or 18 years old and were wearing masks and dark clothing.

Anyone with any information should contact Nottinghamshire Police on 101, quoting incident 569 of 28 February 2013, or call Crimestoppers anonymously on 0800 555 111.
