The attacker was already serving a life sentence for murdering his friend and stabbing a 16-year-old boy
A convicted killer broke the jaw of a Jewish chaplain visiting a Cambridgeshire prison in an attack motivated by racial hate. Joseph Gynane, 41, was already serving a life sentence for murdering his friend and stabbing a 16-year-old boy when he shouted “Allah Akbar” as he attacked the chaplain visiting HMP Whitemoor on September 14, 2025.
The chaplain had been speaking to prisoners on the top floor landing of the prison when Gynane attacked him from behind at just before 2.30pm on September 14. Gynane punched the man to the back of the head with such force that he was knocked to the floor and continued punching him.
The convicted killer continued even while being sprayed with PAVA (a chemical spray designed to incapacitate attackers) by a prison officer. He eventually stopped the attack, and the chaplain was taken to a different part of the prison where he received medical treatment.
He later visited Peterborough City Hospital, where medical checks revealed he had suffered a broken jaw and a broken thumb. The chaplain told officers he believed the attack was religiously motivated due to him being Jewish and wearing a black skull cap at the time.
Gynane was moved to the prison’s segregation unit and covered his cell in graffiti, including the phrases “free Palestine” and “Death to the IDF”. He was charged with racially aggravated assault inflicting grievous bodily harm (GBH) and admitted the offence at a court hearing in March this year.
On Friday, May 1, he was sentenced at Cambridge Crown Court where he was handed 11 years (six years plus an extended five years on licence) on top of his existing life sentence. His life sentence holds a minimum term of 30 years, meaning Gynane will not be eligible for release until at least 2055.
Sentencing, Judge Andrew Hurst said chaplains provided support for prisoners and were “valuable, cherished and should be protected”. He noted that Gynane converted to Islam in 2007 and it was clear he held “antisemitic, florid and ideologically disturbing” views.
Judge Hurst said Gynane had a “long record for serious violence, including stabbings”. He also held an “appalling record for violence within prison”, with the highest number of assaults to his name at HMP Whitemoor.
He said the attack was a “serious assault motivated by racial hatred”. He noted his concern about a “very high risk of future assaults” from Gynane, who “will seek to harm innocent members of Jewish community”.
Detective Constable Emma Purser said: “Gynane was already serving a life sentence for murder, but I am pleased he has now had his sentence extended by quite some time and has faced justice for his actions – which were shocking and despicable.
“The Jewish chaplain involved in this case was providing a valuable service and no-one deserves to be attacked in this way, with such strong violence – and especially not because of their religion.”
