TWO boys who were threatened by a knifeman in Bradford have helped police to create this image of the suspected offender.
The victims, aged 14 and 15, were approached by the man in Peel Park who used a knife to threaten them.
An altercation followed and one of the boys had a mobile phone snatched away by the offender, who ran off towards Otley Road.
The teenagers were uninjured during the incident.
The offender struck about 4.55 pm on Saturday, August 16, and was described as white, late teens or early 20s, slim build, 5ft 6ins tall and spotty, with green eyes. He was wearing a black Adidas padded jacket.
Detective Inspector Alan Flynn, of Bradford District CID, said: "We believe that someone will have seen this man as he ran off towards Otley Road, and I would ask anyone with any information to contact Detective Constable 3312 Singleton at Bradford District CID on 101 or Crimestoppers on 0800 555 111."
