Firefighters returned to a disused college building in Huddersfield this morning for the third time in under a week.
Crews from Huddersfield and Rastrick were called to the former Kirklees College site in New North Road at 5.25am this morning.
A fire had broken out in the first floor of the five storey building.
Breathing apparatus, a large jet and a hose reel were used to put out the blaze.
West Yorkshire Fire Service had dispatched five crews to the site on Saturday at around 5.30pm when a fire was reported.
The service was also called out on Friday evening at around 8.30pm when fires were spotted on the first and second floors.
