POLICE are looking for a robber who knocked a man to the ground and stole his mobile phone.

The 35-year-old victim was on Devonshire Street, in Keighley, when he was approached by the man who pushed him over.

There was then an altercation between the pair and the suspect ran away with the victim's Motorola mobile phone.

The victim suffered a slight head injury, which required hospital treatment.

The suspect is described as Asian, of medium build, and is believed to be in his 20s. He was wearing dark clothing and a hat.

Police are now appealing for witnesses to the incident, which occurred between 9.45pm and 10.15pm on Monday, January 5.

Detective Inspector Richard Partis, of Bradford District CID, said: "This appears to be a totally unprovoked attack, which resulted in the victim needing medical attention.

"I would urge anyone with any information, or who may have seen this male acting suspiciously in the Devonshire Street area, to contact police on 101, or Crimestoppers, anonymously, on 0800 555111."
