Riot police called to high-security prison disturbance
Inmates at Long Lartin prison, Worcestershire, rioted using pool balls as weapons.
A prison wing is back under control after riot officers were drafted in to deal with a disturbance.
Anti-riot prison officers were first sent to Long Lartin prison in Worcestershire to deal with an "ongoing incident".
According to the BBC, up to 80 prisoners are involved in the incident and used pool balls as weapons.
A Prison Service spokeswoman said: "Specially trained prison staff successfully resolved an incident at HMP Long Lartin on 12 October. There were no injuries to staff or prisoners.
"We do not tolerate violence in our prisons, and are clear that those responsible will be referred to the police and could spend longer behind bars."
The disorder at the Category A prison, which has a capacity of 622, was first reported on Wednesday evening.
A steady stream of Tornado team vans could be seen heading onto the prison car park, up until about midnight.
Several prison vans also arrived at the maximum security jail, which is surrounded by acres of countryside.
Beyond the 30ft curtain walls, shouts of inmates could be heard above the barking of prison guard dogs.
