Three teenagers have been arrested on suspicion of arson after fire destroyed part of a school in West Yorkshire.
Flames leapt hundreds of feet into the air at the height of the blaze
More than 100 firefighters tackled the blaze at Airedale High School in Crewe Road, Castleford, on Tuesday night.
The upper school's main hall and dining area was destroyed, but the lower school escaped damage.
The boys, aged 15 and 16, were later released on bail. Earlier in the week, two other teenagers were also arrested and bailed in connection with the fire.
Head teacher Paul Frazer said there was no electricity or heating in parts of the school but lessons would be held on Monday for pupils in years seven, nine and 11.
"As soon as we get classrooms back we'll fill them with students," he said.
"We're concentrating on years nine and 11 as year nine has SATs and year 11 is the GCSE year. We'll rotate the lessons and give pupils work to do at home."
