A convicted murderer has gone on the run from prison for the third time.
Arnold Pickering, 44, from Chadderton, Greater Manchester, failed to return to HMP Kennet in Maghull, Merseyside, after leaving the Category C jail on day release at about 9.30am on Saturday.
Pickering last absconded in December 2009 when he was let out on day release from HMP Kirkham to work on the bins in Manchester city centre.
He was one of eight prisoners taking part in a controversial scheme, run by the Prison Service with Enterprise Manchester, which emptied the bins for Manchester Council at the time.
He handed himself in four days later in Motherwell, Scotland.
Pickering also escaped from Strangeways in Manchester before he went on to stab a man to death in Oldham in 1990.
He was jailed in 1991 for life and ordered to serve a minimum of 18 years.
Pickering had been risk assessed as suitable for temporary release on licence by the Ministry of Justice, said Merseyside Police.
Another inmate, Thomas Moffet, 51, from Blackburn, Lancs, who is serving an indeterminate sentence for a number of robberies carried out in his home town in 2006, also failed to return from day release on Saturday.
Pickering is described as about 5ft 11in, of medium build and with blue eyes. He has tattoos on his arms and chest. Moffett is about 5ft 10in, also of a medium build and with brown eyes. He has tattoos of swastikas on his arms.
