Five boys aged between 11 and 15 are due in court charged over a fire at a school in Leyland last September. Parts of St Mary's Catholic Technology College had to be demolished and extensive re-building is still needed.
The building, which was built in 1957, had no sprinklers.
Lancashire police released a statement confirming the boys from Leyland, have been charged with "arson with intent/reckless as to whether life was endangered and arson with intent to endanger life."
