Firefighters were called to a fire at Norwich Prison.

Four fire engines were called to the Knox Road prison at just after 2.30pm today.

Firefighters arrived at the scene of what was described as a 'building fire' at 2.37pm, but left the scene 20 minutes later without having to take any action.

Last Tuesday, fire engines were called to the prison after a fire was started by an inmate in the segregation unit.

That came as the jail, which holds more than 750 inmates, was said to be operating on a 'skeleton crew' of just 10 officers.

Many staff had stopped working after the Prison Officers Association (POA) directed members in England and Wales to protest.

The organisation claimed officers are being forced to work in an 'unlawful' situation because of a lack of health and safety in jails.
