A paedophile who abused children in care homes has died behind bars.
John Allen was jailed for life, with a minimum term of 11 years, in 2014 for a string of sex offences committed from the 1960s to the 1990s.
He was convicted in 2019 of further sex offenders after other victims contacted police.
Allen ran several homes including Bryn Alyn, in Wrexham, Wales.
The Prison Service has now confirmed the convict has died.
He died at the age of 83 at HMP Bure, in Norfolk, on May 3.
A Prison Service spokesman said: "As with all deaths in custody, the Prison and Probation Ombudsman will investigate."
He had 11 properties which housed more than 150 young people from across the UK.
In the 2019, jurors heard how a victim described being dragged to Allen's office after a fight and pinned to the floor.
The next thing he remembered was his clothes being ripped off and Allen sexually assaulting him.
One former resident at the Bryn Alyn children's home said living there 'wasn't care, it was like hell'.
He revealed how Allen groomed him and gave him gifts before abusing him.
Allen was handed a life sentence in 2014 for 33 sex offences.
He was then convicted in 2019 of seven further counts of indecent assault and one of a serious sexual offence against children as young as 13 in his care.
