Firefighters rushed to get people out of a burning three-story apartment building Wednesday morning in the Auburn Gresham neighborhood.
Paramedics took a child to Comer Children's Hospital in good condition.
Charles Okeke said he couldn't leave his third-floor apartment due to the smoke, CBS Chicago reported.
"I heard the smoke alarm in the building saying, 'fire, fire, fire,' but I couldn't walk down the hallway because it was thick and covered up in smoke. So I had to stand by the window and wait for the good Fire Department of Chicago to help me out," he said.
He was not hurt in the fire that remains under investigation.
