Detectives released this e-fit of a man they want to trace in connection with an attempted robbery on Old Lane in Birkenshaw , Bradford.

An 18-year-old man was walking along the road at about 9pm last Friday when he was approached by the suspect, who asked what kind of phone he had.

The man then grabbed the teenager and assaulted him while trying to grab his property.

He fled empty-handed on foot along Station Lane when a vehicle approached.

The suspect is described as white, in his early 20s, of stocky build and about 6ft tall with dark brown hair that was shaved close at the sides but long on top and ran down on to his neck. Anyone with any information is asked to contact Huddersfield CID on 101 or Crimestoppers on 0800 555111.
