HARVEY, Ill. (WLS) --Three firefighters were injured while battling an auto shop fire near 149th Street and Loomis Avenue in Harvey.
The fire was reported around 9:15 p.m. Tuesday. Workers told police they tried to put out a small, accidental fire but were unable to contain it.
Authorities said the fire spread quickly and flames consumed the building, causing extensive damage. The roof collapsed before firefighters could get the fire under control and several cars burned inside the business. The flames did not spread to any neighboring structures.
