Police are hunting an armed robber who struck at a County Durham post office this morning.
At about 11am a man wearing a balaclava walked into the post office at Mickle Grove, Coundon, and threatened the cashier with a knife before demanding cash.
A large quantity of cash was handed over and the man made off in the direction of Hambleton Road.
The cashier, although unhurt, was left very shaken.
DC Gareth Hodgson, of Bishop Auckland CID, said "Clearly this was a very distressing incident for the casher involved and a large amount of cash has been taken. With this in mind I would urge anyone with information to contact police urgently.
"Fortunately incidents of this nature are rare in our force area and we are currently carrying out a number of lines of enquiry aimed at bringing the person responsible to justice."
Anyone with information should contact police on 101 and quote incident number 0146 of 23/08.
