An armed robber serving a life sentence is the latest criminal to go on the run from Ford open prison.
Police say David Blood, 48, said may pose a threat to the public following his escape.
It is thought to be the second time he has absconded from an open prison after going missing from HMP Sudbury in Derbyshire in April 2012.
Blood is described as 6ft 1in tall (1.85m), of small build with brown eyes and cropped black hair. He is known to have links to Staffordshire and Warwickshire.
