Excerpts from cltv.com:

Around 3 a.m. Sunday, Chris Cammon was waiting for a bus at the corner of 79th Street and Jeffery Boulevard, when he heard the sounds of cars drag racing blocks away. As two cars raced towards the intersection, one clipped the other and crashed into a traffic light pole erupting in fire.  With help from others, he pulled a 24-year-old man from behind the wheel of the burning vehicle, and dragged him across the street to safety.

By 3:15 a.m., emergency responders firefighters were on the scene and put out the flames. The victim survived, and was taken in critical condition to the University of Chicago Medical Center.
