A £3,000 reward is being offered to track down a convicted murder with a history of violence.

Joseph Bagley has been on the run since May after serving 31 years in prison for killing a taxi driver.

The 66-year-old had been living at approved premises in Maidstone, but failed to return for his curfew on Sunday, May 12.

He has not been seen since.

A month after he went missing police issued computer generated images of what the moustachioed murderer would look like if he changed his appearance.

Crimestoppers is now offering a £3,000 reward for information on the whereabouts of Bagley, who is considered dangerous.

He is thought to have links to Kent, Surrey, Buckinghamshire and parts of Scotland.

He is described as white, with blue eyes and grey hair. He is approximately 5 foot 11 inches tall and of medium build. He has a memorial tattoo on his left arm and a scar on one of the fingers on his right hand.

Glenys Balchin, Surrey Regional Manager at the charity Crimestoppers, said: "We believe everyone has the right to feel safe from crime, whether at home, in the workplace or when out and about.

"Bagley has a history of violence so it’s crucial that if you know where he is or spot him, please let us know immediately and do not approach him. He has links to Kent, Surrey, Buckinghamshire and Scotland and may well be in hiding in other parts of the UK that he’s familiar with.

"Please help us to keep our communities safe and do the right thing by contacting Crimestoppers if you know of Bagley’s whereabouts. In over 30 years our charity has always kept its 100% anonymity promise to everyone who trusts us with their crime information.

"No one will know you contacted us and it could be your information, however small, that makes a difference. Our UK Contact Centre is open 24/7 on 0800 555 111 or you can use our anonymous online form at www.crimestoppers-uk.org."
