48-year-old disgraced rockstar Ian Watkins was serving a 29-year jail term for multiple sexual offences, including serious crimes against young children and babies.

He was attacked with a knife by a fellow inmate on Saturday morning, sources confirmed.

West Yorkshire Police said detectives from the homicide and major inquiry team are investigating after prison staff reported the assault on Watkins, who was pronounced dead at the scene.

A Prison Service spokesperson said they couldn’t comment whilst the police investigate.

Watkins was stabbed before whilst in the same prison in 2023, suffering non life-threatening injuries after he was taken hostage by three other inmates before being freed by prison officers six hours later.

He was sentenced to 29-years in prison after admitting 13 sex offences, including the attempted rape of a fan’s baby in December 2013. He also encouraged a fan to abuse her child and secretly stashed child sexual abuse videos, some of which he had made himself.

At the time, police described him as a “committed, organised paedophile”.

When sentenced at Cardiff Crown Court, the singer was told he was being given an extended sentence – and a judge said his crimes “plumbed new depths of depravity”.
