MYSTERY still surrounds a fire which gutted a Swindon school's mobile classroom an investigation is being carried out.

The cause of the blaze at Gorse Hill Infants School is expected to be known later this week but it is not being treated as suspicious.

Nobody was injured in the fire but headteacher Sue Kershaw said she was devastated that 10 weeks of literacy work, which parents and children had worked on together, had gone up in flames.

Two engines and 12 firefighters from Swindon and Stratton attended at about 7.24am last Wednesday but even though the blaze in Avening Street was soon put out heavy smoke meant the school had to close for the day. About 20 staff helped with the clean-up operation and classes went ahead as normal the following day.

Until the mobile, which was used mainly by special needs children and for storage, is replaced, room will have to be found in the main building.

The fire came three weeks after a blaze gutted a computer room at another local school.

St Sampson's Junior School in Cricklade was forced to close two days early before Christmas and pupils had an extra four days off at the end of the break to allow staff to clean up the premises.

Lessons were back on last week as the school tried to get back to normal.
