TOPEKA (WIBW)– A Thursday night fire did $35,000 damage to an auto repair shop.

Topeka Fire says crews found the garage at 1701 SE Madison fully involved when they arrived just before 6:30 p.m., Thursday.

They say the roof collapsed, sending crews into a defensive attack. No one was inside the building at the time.

Investigators believe it was accidental, starting when an electrical appliance got too close to flammable vapors.
