A man robbed at knife point has sparked a police appeal.

The incident happened on Tuesday at 2.10pm in Trevor Road, Hitchin.

The victim was driving his vehicle, a silver BMW, along the road when he was flagged down by a man.

The man got into the vehicle, showed a knife to the victim and demanded money. The offender then took hundreds of pounds of money from the victim before running away towards Walsworth Road.

The offender is described as a white man, aged in his mid-thirties and of slim/medium build. He had straight, short mousey blonde hair that was fairly thin and appeared to be receding. He had pale skin and had slightly pockmarked cheeks. The offender was wearing light grey tracksuit bottoms and a black or navy woollen jacket and possibly blue Nike trainers.

Detective Sergeant Pete Hankins, who is investigating, said: “We are currently conducting a number of enquiries into this crime. Understandably the victim was left shaken by the robbery but thankfully was not injured and these types of incident are not common in Hitchin.

“I am very keen to speak to anyone who may have witnessed this crime or may know who is responsible. This occurred in the early afternoon so it may be possible that other people would have been in the area at the time. I would urge anyone who may have information relating to this incident to please contact the police as soon as possible.”

Anyone with information is asked to contact DS Hankins via the Herts Police non-emergency number 101 quoting crime reference number G1/13/2660. Alternatively call Crimestoppers, the independent charity, anonymously on 0800 555 111.
