Police are appealing for witnesses after a postman was threatened with a knife after completing his rounds in Bicester.

The postman was walking along Woodfield Road when he was approached by a man at about 11.20am yesterday. The man pulled a knife from his pocket and demanded the postman hand over the mail he was carrying.

At this point the postman informed him that he did not have any mail on him and showed him his empty bag. The man then shoved him in the shoulder before running off in the direction of Buckingham Road.

The man was described as white, in his mid-thirties, about 5ft 10ins, with a wiry build and thick facial stubble. He was wearing a dark grey or slate coloured hooded top and stonewash jeans and had a generally scruffy appearance.

Det Con Rachel Fewtrell said: “We are very keen to speak with anyone who may have witnessed this incident, who might have seen this man in the area or who recognises this description.”

Anyone with information should contact the CID team at Bicester via the Thames Valley Police Enquiry Centre on 0845 8 505 505. Alternatively, you can contact the Crimestoppers charity anonymously on 0800 555 111.
