A fire broke out at a junior school in the Harrogate district after a bin set alight.
Firefighters were called to Queen Ethelburgas School in Thorpe Underwood shortly befor 9.30am yesterday (Sunday).
They arrived to find a fire had broken out in a classroom in the science block, causing damage to the floor and the wall.
A crew from Boroughbridge attended, calling for backup from Acomb and York when they saw how much smoke was on the second floor of the building and how difficult it was to access.
In a statement released by the school on Sunday afternoon, a spokesman said: “Within minutes fire officers had extinguished the small fire and ventilated the affected room.
“School estate workers are presently cleaning the classroom and will have it fully functioning by tomorrow.”
A spokesman for North Yorkshire Fire and Rescue Service added: “The cause of the fire is still under investigation.”
