A man with links to Sheffield is among a dozen convicts wanted for absconding from a Derbyshire prison over a 14-year-period between 1992 and 2006.
Derbyshire Police have released photographs and information about 12 men wanted historically for being unlawfully at large.
Christopher Crookshank, aged 59, failed to return to Sudbury prison on October 22, 2001, following a period of temporary release.
Crookshank was convicted on May 18, 2000, at Sheffield Crown Court and was serving a sentence of four years three months for deception offences.
He is described as white and six feet tall with blue eyes. Last seen he was stocky, with thinning and greying ginger hair.
Crookshank is originally from the Nottingham area, but lived Sheffield and had friends in the Long Eaton area of Derbyshire.
Another of the fugitives was serving a life sentence for murder, two for wounding, and five were serving sentences for drug offences.
Assistant Chief Constable Martyn Bates said: “We’re asking the public to help us track down these men. We are doing everything possible to trace and arrest these outstanding prisoners and we have recently reviewed our processes.
“We have also increased dedicated resources to further improve our success, but these men have eluded all our efforts to trace them.
“The men did not previously live in Derbyshire and they committed offences elsewhere. But they could now be anywhere, living under different names, which is why we’re making this public appeal.
“We realise the men are likely to have changed significantly since these photos were taken but we hope the public will be able to give us information that will help us to make arrests.”
Other men wanted for absconding between 1992 and 2006 include Delroy Howe, 45, from Birmingham; Michael Answorth, 54, from Clitheroe area of Lancashire; Albert Squires, 48, from Leicester; Raymond Lenihan, 57, from Birmingham, who was serving a life sentence for murder; and Leslie Warden, 58, from London.
Police are also looking for Dutch national Frank Nochel, 49, who was sentenced for drug importing-related offences at Manchester Crown Court in 1998; James Joyce, 42, from Huddersfield; Paul Thomas, 46, from Chester; John Barlow, 39, from Chester; Sylvester Patterson, 38, from Romford in Essex; and Suleman Tahir, 44, from Salford.
