Police are offering a £5,000 reward for information on the whereabouts of a 'very dangerous' convicted murderer who is on the run after being released from jail on licence. William Kerr, 53, is believed to have travelled to London after disappearing from approved premises in Hull. He was released on licence in January after spending 17 years in jail for the murder of Maureen Comfort, who was found dead in 1996. Hunt: There is a £5,000 reward for information leading to the arrest of convicted killer William Kerr, pictured . Crimestoppers is now offering a reward for information that leads to the arrest of Kerr - who police said must return to prison 'as a matter of urgency'. A spokesman said: 'Police have described Kerr as a very dangerous man and it is urgent that he is returned to prison after this breach of his licence. Victim: Maureen Comfort was found dead in January 1996 after being murdered by Kerr and Christopher Moody . 'We understand that it might be someone that knows him personally who is aware of where he is, and for that reason, I would urge you to contact Crimestoppers, completely anonymously, safe in the knowledge nobody will ever know you spoke to us. 'Do the right thing and tell us where Kerr is.' North Yorkshire Police have previously warned members of the public not to approach him but to call 999 if they spot him. Officers believe Kerr, who has links to the Humberside and West Yorkshire areas, may attempt to book in to a hostel in London under a false name. He was released from HMP Stocken in Rutland on January 23, and police announced last week that he had gone missing. Appealing directly to Kerr, Detective Inspector Eamonn Clarke of North Yorkshire Police 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.' Kerr, who speaks with a Scottish accent, was jailed along with Christopher Moody for the murder of 43-year-old Maureen Comfort, whose body was found in a cupboard in her flat in Leeds. She was last seen alive on December 4, 1995, and her strangled body was found by relatives on January 8, 1996. To qualify for the reward, anyone with information should contact Crimestoppers directly over the phone or online.
