A convict known as Britain's "most dangerous prisoner" has reportedly been moved to a different prison after spending over 40 years in solitary confinement in a glass cell.
Robert Maudsley, 71, has been behind bars since 1974 after handing himself in to police after garotting and killing a man.
While incarcerated, he went on to kill a further three inmates - including two in one day - horrifyingly hacking at one of their heads with a makeshift dagger before calmly walking into the wing office with the bloody weapon and informing staff that roll call would be two people short.
He gained the nickname of "Hannibal the Cannibal" after reports that claimed he ate one of his victims' brain, which was later said to have been a false report.
After these incidents, Maudsley was deemed too dangerous to be around other people and was put into solitary confinement.
He was imprisoned in a custom-built glass box measuring 18ft by 14ft, which is located underneath HMP Wakefield prison.
Maudsley went on to gain the world record for the most consecutive days in solitary confinement, having been locked up in the cell since 1983.
The glass box has bulletproof windows, and has a toilet and sink bolted to the floor, as well as a table and chair made from compressed cardboard to ensure Maudsley is not able to fashion weapons from anything within.
According to reports, Maudsley previously described his quarters as a "concrete coffin" in a letter to prison authorities, claiming that they had kept him there so he was "out of sight and out of mind".
He has spent many years pleading to be moved to better conditions and has reportedly now been moved to another facility.
According to The Mirror, Maudsley went on hunger trike last month after his Playstation and TV were allegedly removed.
He has now reportedly been moved 125 miles away to HMP Whitemoor in March, Cambridgeshire, where he has been place on a unit for inmates with personality disorders.
Loveinia Grace MacKenney, 69, who has exchanged letters with Maudsley for around five years, told the outlet: "They have put him with 70 other prisoners on a wing.
'It is a disaster waiting to happen. He does not want to be alongside other men because of the abuse he suffered as a child.
"You can tell from his letter to me what a terrible state he is in, his handwriting is shaky. He no longer has his TV, he has no radio. He was a model prisoner on his own, but I think they have targeted him."
She added that she believes he is being "victimized" for "no reason".
Maudsley, the fourth of 12 children, had a traumatic childhood in Liverpool where he and his three older siblings spent their early years in a Catholic orphanage.
Their parents retreived the four children when Maudsley was eight, after which he was subjected to routine physical abuse from his father until he was removed from his parents' care by social services.
Maudsley later claimed he was raped as a child by his father, which left him with deep psychological scars.
In his teens, Maudsley was a sex worker in London, were he was forced to seek psychiatric help after several suicide attempts, and told doctors he heard voices telling him to kill his parents.
Maudsley killed his first victim, John Farrell, in 1974 after he allegedly showed Maudsley photographs of child abuse he'd committed.
After the killing, Maudsley surrendered himself to police, telling them he needed psychiatric care and was sent to Broadmoor Hospital after being deemed unfit to stand trial.
In 1977, Maudsley and another prisoner lured child molester David Francis into a cell where they tortured him for nine hours before killing him.
He went on to kill two inmates at HMP Wakefield - Salney Darwood, who was serving a sentence for killing his wife, and William Roberts, who tried to strangle and rape a four-year-old girl.
Maudsley stated that his victims were rapists, pedophiles, or sex offenders, and that those are the people to whom he is a threat.
He is serving a whole-life sentence without possibility of release.
