A manhunt has been launched in the Vale after a murderer went on the run from prison with another inmate.
Darren Douglas, 46, originally from Birmingham absconded from the Springhill open prison in Grendon Underwood in the early hours of Sunday morning.
He was serving a life sentence for a murder he committed in Birmingham in 1998, where he stabbed a man during an altercation outside a pub.
Douglas is joined on the run by Ricardo Dunn, 32, previously from Lancashire, who was serving an indeterminate sentence for GBH with intent in Burnley, where he assaulted a man following an argument in the street in 2009.
Ch Insp Olly Wright, deputy local policing commander for the Aylesbury Vale area said: “We are keen to speak to anyone who may have seen these men in the area and can provide us with information about their movements.
“These men were both convicted for violent offences and I would advise anyone who sees them to not approach them and call police immediately.
“Both men have links with other areas so may have travelled out of the Thames Valley to those areas.
“I would like to remind people that it is a criminal offence to harbour these men and anyone caught doing so would be arrested.”
Anyone with information about the location of these men should contact Thames Valley Police via the 24-hour enquiry line on 101.
