CHICAGO -- A Chicago firefighter was injured and 21 people were displaced in an extra-alarm blaze early Sunday at a three-story apartment building in Pilsen.
The fire began in building in the 1900 block of South Wolcott and spread to a second building.
Chicago Fire Department Assistant Deputy Fire Commissioner Mark Nielsen says when firefighters arrived on the scene, there were residents in the windows, trying to escape the flames.
He said one resident was rescued by a civilian who used a forklift from a nearby business.
One firefighter suffered a minor injury and was taken to Rush University Medical Center.
Nielsen says the fire was on all three floors of the building and the stairwell was fully engulfed.
The fire was put out at 3:18 a.m.
Paramedics at the scene treated one person, but they were not transported to a hospital.
A total of 21 people, including several children, were displaced.
The Red Cross is working with those residents.
The cause of the fire is under investigation.
