Police have arrested five boys aged between 11 and 15 on suspicion of arson following a school fire in Lancashire.
The blaze broke out on Sunday afternoon at Leyland St Mary’s High School on Royal Avenue.
At one point, 125 firefighters and 20 fire engines were tackling the fire.
The school, which was built in 1957, had no sprinklers.
Lancashire Police announced on Twitter: “Five boys in total, aged between 11 and 15, have now been arrested on suspicion of arson following the fire at Leyland St Mary’s High School.”
They were later released on police bail until September 30.
It is understood that CCTV footage from the school’s cameras shows a group of youths at the rear of the school on Sunday afternoon at around the time the fire started.
