There are currently five men being hunted by Suffolk police, with one being missing for over three years.
The force's wanted list dates back to November 2018, with several of the wanted men having absconded from Hollesley Bay Prison, eight miles from Woodbridge.
The police are asking for the public to provide information that would bring them back into custody - but have warned people not to approach them.
Richard Reynolds
Reynolds, 58, is wanted on recall to prison after breaching the terms of his licence.
Also known as Joseph Cronshaw, Reynolds is described as white, 6ft tall, of medium build and with white hair.
He previously resided in Lowestoft and it is believed he is still living in East Suffolk, but also has links to the City of Westminster area of London.
Phillip Emery
Emery, 45, from Newmarket, is wanted on recall to prison.
He is described as white, about 1.65m or five feet, 4 inches tall tall, of a thin build, with blue eyes and short grey hair.
Police suspect he is highly likely to remain in the Newmarket area but could travel to Cambridge, Thetford or Bury St Edmunds.
Gerry Sargeant
Sargeant, 61, was due to return to Hollesley Bay on September 9, 2018, after being released on temporary licence to attend a work placement in Bury St Edmunds.
He was last seen leaving the prison on a red Honda 125cc motorbike registration number AO11 VMZ, wearing "motorcycle clothes".
Police warn that he was serving a 15-year sentence for robbery and theft, and the public should not approach him.
