Watkins, 48, died while serving a 29-year sentence for child sex offences, sources have confirmed to the PA news agency.
He was attacked with a knife on Saturday (October 11) morning, according to the sources.
West Yorkshire Police have confirmed the death of a man at HMP Wakefield but the man’s identity has not been confirmed at the time of writing.
Sky News reports that Watkins was stabbed in a separate incident at the same prison back in 2023.
Watkins, 48, was jailed in December 2013 with a further six years on licence after admitting a string of sex offences, including the attempted rape of a fan’s baby.
The disgraced singer was arrested following the execution of a drugs warrant at his Pontypridd home on September 21, 2012 when a large number of computers, mobile phones and storage devices were seized.
Analysis of the equipment uncovered Watkins’ depraved behaviour.
A statement from West Yorkshire Police about the incident today (October 11) said: “At 9.39am this morning (Saturday), police were called by staff at HMP Wakefield reporting an assault on a prisoner.
“Emergency services attended and the man was pronounced dead at the scene a short time later.
“Detectives from the Homicide and Major Enquiry Team are investigating and inquiries remain ongoing at the scene.”
A Prison Service spokesperson said: “We are aware of an incident at HMP Wakefield which took place this morning.
“We are unable to comment further while the police investigate.”
