Britain's most dangerous prisoner outraged at latest treatment after spending 48 years in solitary confinement

Robert Maudsley, sometimes described as Britain's most dangerous prisoner, has complained about the conditions he is being kept in.

The 73-year-old is a convicted serial killer serving a life sentence, most of it spent in HMP Wakefield, a category A prison nicknamed 'Monster Mansion' due to the number of high-profile criminals incarcerated there.

In 1974 he killed John Farrell, who had picked Maudsley up for sex and showed him images of child sexual abuse, with Maudsley being sent to Broadmoor Hospital after turning himself over to the police and saying he needed psychiatric help.

While at Broadmoor he and another inmate tortured and murdered child molester David Francis in 1977, with Maudsley then being sent to HMP Wakefield where he killed another two inmates, sex offender Salney Darwood and paedophile Bill Roberts.

He has spent several decades in solitary confinement which he once described as 'one long period of unbroken depression' before last year being moved to HMP Whitemoor, and the Daily Mail reports that in a phone call to a relative he has made complaints about the way he's been treated in his confinement.

Maudsley turned 73 last month and had a phone call with his nephew Gavin in which he complained about the increase in security level.

In the call he said: "The fact is, for the last 13 months, they've not allowed me to have any visits whatsoever, because they put me on closed visits.

"What they're actually saying is, 'we want you to talk to staff'.

"I'm locked in my cell 22 hours a day, and the only exercise I get is on the exercise yard. I'm not going to use my time in the fresh air and on the exercise yard, talking to people who are actually abusing me."

In his call to family, Maudsley said he was also unhappy that the guards who were outside his cell and escorted him around the prison didn't come and speak to him.

He described the way he was being treated as 'actual insanity' at the staff wanting him to talk more to them but them not making an attempt to speak with him.

"I'm stuck in my cell 22 and a half hours a day. If they want to talk to me, all they have to do is come to my cell and say, 'Bob, do you want to have a talk?', or 'Bob, do you want to engage?'

"For 13 months, not one member of staff has ever come to my cell asking me to talk to them or asked me to engage with them – not one.

"That's how they treated me, and they expect me then to actually speak to them."

He said he planned to go on hunger strike, and had applied for a 'group association' with two other prisoners, though said he didn't want to be near prisoners who were 'paedophiles or sex offenders'.

Maudsley said he wanted to be allowed to play chess with a fellow inmate, saying it would benefit the mental health of both of them.
