A Chicago firefighter was injured Monday while fighting a fire in a vacant south side factory.
First responders were called to the abandoned building, in the 4800 block of S. Halsted St., shortly before 6 p.m. and quickly elevated the fire to two alarms.
One firefighter was injured and taken to Northwestern Memorial Hospital, the fire department said.
The building was "fire resistant" and the blaze was contained in about 45 minutes, according to the fire department.
The cause of the fire was not known Monday night.
The fire is about two miles southeast of a five-alarm fire gutted a vacant warehouse Jan. 24. It took more than 170 firefighters to extinguish that blaze, which was caused by an open flame.
