FIRE crews spent around four hours dealing with a blaze at a former school in Bradford last night. 

Crews from Bradford, Odsal, and Cleckheaton were called to the former Yorkshire Martyrs School in Westgate Hill Street, Tong - next to Tong High School - just before 8pm last night. 

The fire is thought to have been started deliberately. 

A spokesman for the Bradford crew said firefighters had managed to contain the blaze within the school's old assembly hall. 

Around 25 per cent of the ground floor of the two-storey building, measuring around 60m by 50m, was said to have been involved in the fire. 

Crews were at the scene until around midnight to make the disused building safe. 

It is not yet known whether the building will have to be demolished. 

Fire crews did not see anyone at the site, but said there had been signs of previous break-ins to the building. 

The former school, which closed in 2010, was previously hit by fire in 2011 and 2015.
