A CONVICTED murderer who has gone on the run is believed to be in the London area, North Yorkshire Police said tonight.

William Kerr, 53, who speaks with a Scottish accent, is wanted for emergency recall to prison after breaching his release licence.

Detective Inspector Eamon Clarke of the North Yorkshire force said Kerr may be trying to book into a hostel or other accommodation using a false name. The Metropolitan Police have now joined in the search.

"We ask that you do not approach Kerr, as he is considered dangerous," he added. "You should contact the police straight away on 999 and officers will be dispatched to arrest him or investigate the sighting."

Appealing directly to Kerr, DI Clarke said: "William, you know you have breached your licence conditions, and by continuing to do so you are only making things worse. It is now time to do the right thing and hand yourself in to the police."

He was jailed for life for murder at Leeds Crown Court in June, 1998 and was released on licence on January 23 this year.

Kerr absconded from approved premises in Hull.

Anyone who sees Kerr or knows where he is should call 999 and pass the details to North Yorkshire Police stating the "William Kerr appeal".
