Firefighters helped evacuate a Derbyshire school as a blaze tore through the roof space above two classrooms.
The blaze was reported at Stonebroom Primary School in High Street about 1.30pm yesterday.
Derbyshire fire service area manager Peter Aykroyd explained there had been a fire in the roof of a single story annex which is currently covered by scaffolding.
He said: “The cause of the fire is not known. We do not suspect anything deliberate.
“We believe it was accidental.”
Three appliances, including two reserve crews, were called in due to yesterday’s strike with one duty retained pump.
Area manager Aykroyd said the fire was contained to the extension and that crews had salvaged some school work.
The building suffered some damage to the two rooms below the roof space. The site was set to be re-examined later by fire investigators.
A spokesman for Derbyshire County Council said the school is closed today.
He added: “The roof above one of the classrooms has completely collapsed and three other rooms are damaged.”
