Mansfield school fire was arson
A fire at a former Nottinghamshire school is being treated as arson by police.
About 60 firefighters tackled the blaze at the Sherwood Hall School in Forest Town, Mansfield, on Monday.
Police have said there will be no further examinations of the scene due to concerns about officers being exposed to asbestos.
Mansfield District Council is in the process of clearing and securing the building's remains.
Anyone with information about the cause of the fire has been asked to contact police.
A number of residents were evacuated from the area between 1100 BST and 1600 BST and were advised to keep windows closed.
Fire crews remained at the site overnight to damp down the buildings.
