Charles Bronson might be one of Britain’s most notoriously violent inmates, but that hasn’t stopped him from being a target behind bars, his brother has said.

The prisoner was apparently threatened with beheading after a disagreement with fellow inmates held in HMP Full Sutton over their Islamic prayer rituals.

Mark Peterson, Bronson's brother, was quoted by Wales Online as saying: "He’s been having some verbals and they threatened to cut his head off.

"I’m not sure how it started but they were up all night praying and kept him awake so there was some verbal."

"There were some threats made by these Muslim extremists," he added, saying that Charles, 61, had asked them to "pipe down".

Unsurprisingly, however, he’s not worried about his brother's safety.

"They will never see each other so they will never get the chance to confront each other," he said. "He can handle himself OK for a 61-year-old man."

The Ministry of Justice for HMP Full Sutton said that they were unable to comment on individual prisoners.

Last week, Bronson was sentenced to a further two years in jail for attacking a prison governor.

The attack occurred in a TV room in Woodhill Prison, Milton Keynes, on 28 April.

The governor sustained bruising to his torso, arms and legs from the outburst.

Bronson, now known as Charles Salvador, is believed to have been angered after he had learned that prison staff had withheld "enormous amounts" of mail from him.

His reaction was taken into account as mitigating circumstances, and the judge called for the jail to launch an investigation into the incident.

Although his injuries were not severe, the judge said that Bronson’s history made the crime all the more terrifying.
