Notorious criminal Charles Salvadore has been rowing with Islamic inmates who threatened to cut off his head in a clash over noise, his brother has claimed.
Salvadore, one of Britain's most notorious prisoners, got into an argument with Muslim inmates who kept him awake at night whilst reciting prayers.
His brother says Salvadore told the inmates to pipe down, and they threatened to "cut off his head" at HMP Full Sutton in Yorkshire.
Salvadore's brother Mark Peterson told the Sunday Mirror: "He's been having some verbals and they threatened to cut his head off.
"There were some threats made by these prisoners. I'm not sure how it started, but they were up all night praying and kept him awake so there was some verbal."
He said Salvadore – who has convictions for armed robbery, wounding, wounding with intent, criminal damage, grievous bodily harm, false imprisonment, blackmail and threats to kill – told them to "pipe down".
"They will never see each other so they will never get the chance to confront each other," Mark said, adding he was not worried about his brother. "He can handle himself okay for a 61 year-old man," he said.
Salvadore, who at one stage converted to Islam and changed his name to Ali Ahmed before denouncing the religion, recently changed his name to Charles Salvador from Charles Bronson in a move to leave his criminal reputation behind.
