Three fire crews were called to a blaze at Norwich prison earlier this afternoon.

Units from Sprowston, Carrow and Earlham were called to the fire at the prison on Knox Road just after 12pm.

The fire was extinguished before the arrival of the brigade but crews used a thermal image camera to check for hot spots. All three crews had left the scene by 12.20pm.

A prison service spokesperson said: 'Staff at HMP Norwich put out a small cell fire on Tuesday 17 January. There were no injuries to staff or prisoners and the fire service attended as a precaution.'

It follows a blaze during a prison officer protest in November in which an inmate set fire to his cell.
