An on-the-run prisoner could be heading for West Yorkshire, police have warned.

Sex offender Sean Cawthray, 41, absconded from HMP Leyhill, South Gloucester shire, on Sunday.

Avon and Somerset Police say that Cawthray (pictured) has links to West Yorkshire.

He was locked up indefinitely in 2002 after attempting to kidnap a 14-year-old girl at a bus stop on the outskirts of Leeds. He had previously served two jail terms for rape.

Anyone spotting him should not approach him but call 999.

He is described as white, 5ft 9ins to 5ft 11ins tall, of medium build with short brown hair and blue eyes. When last seen he was wearing a pair of silver coloured training shoes, cream coloured combat trousers and a light blue coloured Helly Hansen type top.

He could have been wearing either a worker's fluorescent jacket, grey jacket with orange patches or black jacket with a blue patch.
