Assaults on staff at Wormwood Scrubs rocketed by 78% in 2015, new government figures have revealed.
Data obtained by getwestlondon from the Ministry of Justice shows staff at the prison were assaulted 123 times last year, compared to 69 the year before.
The figures come as staff at the jail, in Du Cane Road near White City, walked out on Friday (May 6 ) amid concerns over health and safety.
The 2015 figure is a record high for the Victorian-built prison according to data going back to the turn of the century, and is the only the second time assaults on staff has topped 100 in a calendar year.
Fourteen of the attacks last year were classed as serious, a joint-record for Wormwood Scrubs .
Offences fall into this category if assaults are sexual in nature, result in someone going to a hospital outside the prison, require treatment for concussion or internal injuries or cause some external ones such as burns, stab wounds or bone fractures.
'Violence against our staff not tolerated'
Prison staff, who are members of the Prison Officers’ Association (POA), walked out of Wormwood Scrubs on Friday because of serious safety concerns.
General Secretary Steve Gillan spoke of a significant increase in attacks on prison staff and said with drugs and alcohol “easily accessible” to inmates.
Responding to the new set of data he said: “These figures are truly shocking and I am sure the general public will have sympathy with prison officers who do a tremendous job in keeping the public safe. Our prisons are in crisis and Government appear to be in denial”.
A Prison Services spokesperson said: “These figures demonstrate the very serious challenges facing the prison service . They show how badly prison reform is needed.
“The safety of our staff is paramount and violence against them is not tolerated.
"When incidents do occur we work with the police and Crown Prosecution Service to ensure they are investigated and prosecuted to the full extent of the law.
“We have also secured £1.3 billion to modernise the prison estate and will work to reduce violence in our prisons by giving governors and those who work in prisons the tools they need to rehabilitate offenders.”
