A convicted killer on the run may be disguising himself under various different looks, according to police who are appealing for information on his whereabouts.
Joseph Bagley, 66, was jailed for life with a minimum term of 20 years in 1978 for the murder of a taxi driver, but was released from prison on a supervised life licence in January.
Surrey Police said they believe Bagley is likely to have changed his appearance since going missing and have released a forensic artist's impressions of what he might now look like.
He had been living in Maidstone, Kent, but has not been seen since May 12.
Bagley, who is believed to have links to Scotland, as well as the Kent, Surrey and Buckinghamshire areas, failed to turn up for his curfew later that day.
He is described by police as white, approximately 5ft 11 tall, and of medium build, with blue eyes and grey hair.
He has a memorial tattoo on his left arm, and a scar on one of the fingers on his right hand.
Police have previously warned that Bagley could "lash out" and advised people not to approach him.

Detective Inspector Mark Parry said: "We are pursuing all possible lines of enquiry with regards to Joseph Bagley's whereabouts, but we need the public's help to find him.
"I believe that he could lash out if he feels threatened, or that he is going to be returned to prison, so I am asking the public not to approach him. If you know where he is, or have information that could help us to locate him, I ask you to call police immediately on 999, quoting reference number PR/45190050312.”
Bagley previously went on the run in 1994 after escaping during an escorted home visit to an elderly relative in Woking, Surrey from Coldingly prison, Weybridge.
He was recaptured more than a month later in January 1995.
