Firefighters fought a three-alarm fire Sunday in a repair shop in Marlow Heights for longer than an hour.
Three cars and a RV in the repair shop of a Pontiac dealership at 5001 Auth Way caught fire about 11:30 a.m., prompting a blaze that took 50 firefighters longer than an hour to extinguish, said Mark Brady, a spokesman for the department. A group of 25 firefighters were standing by as a precaution, Brady said, but did not become involved.
The blaze caught on the roof of the building, forcing firefighters to evacuate and attempt to control the fire from outside, Brady said.
No injuries resulted from the blaze, Brady said, and investigators determined the fire was caused by an electrical malfunction.
Estimated damages total $500,000, Brady said.
