Firefighters from Afton and Creston responded to a hog building fire Thursday night, in Union County, north of Afton. The first call went out at 11:45-p.m. The structure had already collapsed by the time the first crews from Afton arrived on the scene located off of Pheasant Avenue.

Crews from both departments worked to contain the flames and to prevent a nearby propane tank from exploding. No animals were lost in the blaze. It’s not clear how the fire started. Firefighters were on the scene for about three hours.
