INVESTIGATORS say a blaze in a building in the grounds of Penair School, Truro last Wednesday morning was started deliberately.

Two fire crews from Truro and one from Falmouth were called to the blaze at the school in St Clement Hill at 3.43am on January 3.

When they arrived they found the building, approximately 10m x 5m, was well alight. The crews wearing breathing apparatus used two hose reels and two hose reel jets to extinguish the fire.
