A murder investigation has been launched into the death of a man who was jailed for the murder of a 60-year-old man in Northamptonshire two years ago.
John York, aged 25, was pronounced dead on Sunday at HMP Long Lartin in Worcestershire after he was found seriously injured in a cell.
A statement from West Mercia Police said his death followed “an alleged encounter with two other prisoners”. Two men, aged 30 and 46, have been arrested on suspicion of murder.
York, of Crouch Road in Irthlingborough, was found guilty of the murder of 60-year-old Glenn Clary at an address on the same road in August 2012.
At the time of his trial he pleaded guilty to manslaughter on the grounds of a dependency on alcohol and was convicted along with 46-year-old Jenny Ryan and 65-year-old Gary Monaghan.
They were accused of punching, kicking and stamping on Mr Clary after he was found with broken ribs, brain damage and a ruptured liver. All four had been drinking heavily.
York was also convicted of a separate robbery of a 26-year-old man eight days before the death of Mr Clary.
Detective Inspector Mark Bellamy, leading the investigation into York’s death, said: “We are currently working to ascertain the exact circumstances surrounding the death of Mr John York and our priority is to ensure those responsible are brought to swift justice.
“I would like to take this opportunity to pass my condolences to the victim’s family at what must be a very difficult time.”
