A convicted child killer who absconded from prison may be living rough, police have said.
West Mercia Police said they are following up possible sightings of Alan Giles across the South Warwickshire area.
The 56-year-old, who absconded from HMP Hewell in Redditch, Worcestershire, at about 11am on Monday, was reportedly seen in Inkberrow on Thursday night.
Police went to the village in Worcestershire yesterday and are there again today, a force spokesperson said.
Giles, originally from the Oldbury area of the West Midlands, was given a 19-year tariff for the 1995 kidnap and murder of teenager Kevin Ricketts.
The 16-year-old victim's body was not found until 1998, after Giles asked to speak to detectives from West Midlands Police while serving his sentence.
Giles, who has had recent contact with family in the West Midlands, is described as white, 5ft 9ins, and of proportionate build with short grey hair and blue eyes. He has tattoos of an eagle on his back and a swallow, shark and flower on his left arm.
It is believed he is wearing a grey Rockport sweater, blue jeans and white Asics trainers.
Giles, who would have been eligible to apply for parole next year, is believed to have absconded from an "open" section of the prison on foot.
Staff at the jail checked on Giles at 6am on Monday, when he was in his cell, but found he was missing at 11am.
No one else is thought to have been involved in helping the on-the-run killer, who may have used the public transport network to leave the area.
It is understood measures have been taken to ensure the safety of members of Kevin's family, who have been informed that Giles is at large.
Detective Chief Inspector Paul Judge said: "We would like to thank the public for their help so far with our investigation. We have had several sightings of Giles in the South Warwickshire area reported to us and we are following up that information.
"It is vital that if anyone spots Giles they do not approach him but call us on 999 or 101 as soon as possible.
"Giles could be sleeping rough in woodland or farm buildings and we would appeal to dogwalkers, farmers, gamekeepers and others to keep their eyes peeled and stay alert".
