The singer from Pontypridd in Wales was serving a 29-year jail sentence – with a further six years due to be served on licence – for a series of horrific child sex offences, including the attempted rape of a baby.

West Yorkshire Police say in a statement that two men have been arrested. The statement reads: "Detectives have launched a murder investigation after the death of a man in HMP Wakefield.

"Officers were called by staff at the prison at 9.39am on October 11 to reports of a serious assault on a prisoner. A man aged 48 was found with serious injuries. Despite medical attention he was pronounced dead at the scene.

"Two men aged 25 and 43 have been arrested on suspicion of murder and are currently in police custody."

Meanwhile, Watkins' ex girlfriend, who was instrumental in bringing his horrendous crimes to light, has described his death as "a relief".

Joanne Mjadzelics tells the Daily Mail: "This is a big shock, but I'm surprised it didn't happen sooner. I was always waiting for this phone call. He was walking around with a target on his back from the first day he entered the prison.

"I have always been scared of him getting out and tracking me down or something, so this is a relief.

"I wanted him dead for a long time after everything he did. I am relieved, I feel like a weight has been lifted from my head."

Watkins was the focal point of high-flying Welsh rock outfit Lostprophets, but his spectacular fall from grace came as a result of being caught and arrested for his brutal crimes in 2012.

He was charged with sexual offences that included the attempted rape of a one-year-old girl and grooming another person – a woman believed to be a Lostprophets fan – to sexually abuse her child, as well as the possession of child pornography and animal pornography.

After initially pleading not guilty, Watkins changed his plea to guilty and was sentenced in December 2013.
