A 200-strong prison riot concluded late on Sunday night after inmates reportedly ripped up toilets and set off a series of fires.

Prisoners at HMP Bedford also allegedly grabbed batons from guards, stole medical gear, carried blades and shared videos on the internet.

Authorities said the chaos fizzled out and was “successfully resolved” by 11.30pm after emergency services were called.

Injuries included a man with a broken jaw, a second with chest pain and a third with back pain.

Inmates will be transferred to other jails throughout Monday after the Prison Officers Association (POA) said 200 were involved.

The Prison Service said: "Specially trained prison officers and staff from the emergency services have successfully resolved an incident involving a number of prisoners at HMP Bedford.

"An investigation into this incident will take place.

“We are absolutely clear that prisoners who behave in this way will be punished and could spend significantly longer behind bars."

Bedfordshire Fire Service was called to the prison at around 5pm.

Footage showed inmates appearing to smash windows, wearing blue medical gloves and wearing medical bibs.

It has been reported there were loud bangs “like gunfire” heard and that prisoners ransacked guards’ officers during the six-hour incident.

Private chemical-treatment contractor trucks were seen waiting outside the Category B jail, opened in 1801 and holding around 500 inmates, along with police vehicles and dog units.

Lewes prison, once described as "worse than Syria", also witnessed a riot last month.

Steve Gillan, POA general secretary, said: "The POA has been warning about this situation of violence in our prisons - it would appear it's coming to fruition.

"I just hope there's no prisoners or indeed prison officers injured in the violence."
