Police say that the fire that ripped through a classroom at County Upper School in Bury St Edmunds in the early hours of this morning is being treated as arson.
The school had to be closed for the day except for students sitting their A-level exams. This was because heating and lighting had to be switched off in order to investigate the fire.
Fire engines from Bury attended the incident which was in a science block at 00.57am and further engines attended from Ixworth, Elmswell, Wickhambrook and Newmarket as well as the fire service’s Ipswich headquarters.
Police say that offenders broke into classrooms by smashing windows before setting a fire in the science block, causing extensive damage.
Someone was seen walking away from the school along Anglian Lane at the time of the fire. They walked towards the Howard Estate possibly through Legrice Walk.
Police want to speak to this person as they may hold important information about the fire. They are described as 6ft tall, of slim build and wearing a dark top with a hood or a hat, and tracksuit bottoms with white stripes down the sides.
The school is due to reopen on Monday.
