A fire at a secondary school in Sussex is being treated as a crime, police confirmed tonight.
It broke out on the third floor of the building at the Millais School in Horsham on Thursday afternoon.
Examinations at the school suggests that the fire was started either deliberately or recklessly. No staff or students were injured in the blaze. It's likely that there will be a police presence at the school for a number of days.
Sussex Police said: "Officers, supported by fire service staff, are working closely with Millais School to ensure that this investigation can be progressed effectively whilst minimising the continued disruption to the pupils, staff and daily functioning of the school."
