Firefighters battled a deliberate blaze at a disused Co Antrim school overnight.
Crews were called to the former Parkhall College site in Antrim just before 2.50am this morning, Tuesday, June 4.
Firefighters from Antrim, Ballymena and Springfield were at the scene for nearly three hours trying to bring the blaze under control.
The fire service said it was being treated as arson and added that "deliberate fires are a drain on resources".
Group Commander Dermot McPoland told Belfast Live: "We got the call at 2.47am from a mobile phone and were told a derelict building was on fire. At the height of the call we had four appliances and the aerial platform in attendance and 24 officers.
"Deliberate fires are a waste of resources and impact on the community taking crews away from areas, the aerial ladder came from Belfast.
"People setting these fires need to cease, they are putting themselves and firefighters in danger doing this."
