Paedophile rock singer Ian Watkins will be serving out his jail sentence in a prison home to some of Britain's most notorious sex offenders and killers.
The former Lostprophets frontman today began a 29-year custodial term for his attempted rape of a baby as well as a string of other child sex offences - which a judge said plumbed new depths in depravity.
While on remand he has been at HMP Parc in Bridgend, but his permanent home will now be HMP Wakefield in Yorkshire - the largest high security prison in western Europe and nicknamed "Monster Mansion".
Prisoners include notorious paedophiles such as April Jones' killer Mark Bridger and Steven Barker who murdered 17-month old Peter Connelly - also known as Baby P.
The prison was also where serial killer Dr Harold Shipman hanged himself in 2004.
As well as being far away from the few supporters he has left, Ian will be coming face-to-face with some of Britain's most serious sex offenders.
Former fans of Ian - who described his sex attacks on babies as "mega lolz" - said they had no sympathy for the Better Off Dead singer.
Scores of them have posted messages on social networking sites such as Facebook and Twitter predicting Watkins would not last "five minutes inside the Monster Mansion".
One wrote: "I hope Ian Watkins gets what he deserves in Wakefield Prison. I have no forgiveness in my heart for him."
Another added: "Mark Bridger was slashed in Wakefield Prison a few months back. Wouldn't suprise me if someone tried to attack Ian Watkins there.
"The prison authorities will have their work cut out trying to protect him - especially given his celebrity status."
As well as keeping Ian behind bars and away from the public, prison officials will try their best to rehabilitate him over the many years of his detainment.
The earliest he will be eligible for parole is in 2031 - when he is 55 years old. If he is to serve the full 29-year custodial term, he will be aged 65.
Sentencing Judge Mr Justice Royce said Watkins' lack of remorse was a decisive aggravating factor in his decision to hand Watkins a substantially higher jail term than usual.
The day after he finally confessed to his crimes, while on remand in a South Wales unit, he told a female friend via telephone: "There's a lot of f****** meaningless bull**** being said that I did when I was f****** off my head.
"I'm going to put out a statement (after being sentenced) just to say it was mega lolz. I do not know what everybody is getting so freaked out about. Nobody got hurt."
Ian was sentenced at Cardiff Crown Court on Wednesday. H e confessed to 13 offences - two counts of attempted rape and sexual assault of a baby, and two counts of aiding and abetting another person to abuse an infant.
He also admitted to owning 90 child porn images - some of which he had made himself - as well as possessing 22 extreme pornographic images relating to animals.
Two accomplices, Woman A and Woman B, were jailed for 14 years and 17 years respectively.
Meanwhile, South Wales Police is investigating whether Ian also committed offences in Germany and America, a nd a separate probe by the Independent Police Complaints Commission (IPCC) is under way.
The IPCC is investigating whether three police forces did not act soon enough on information given to them about Ian.
South Yorkshire, Bedfordshire and South Wales are being investigated over information received about Ian before his arrest in December 2012.
Three other forces - Essex, West Yorkshire and the Metropolitan Police - also supplied information that they had been given about Ian for the inquiry but are not currently under investigation.
