Excerpts from nbcchicago.com:

A massive fire in a Westmont apartment complex sent dozens of people running for their lives Wednesday morning.

The blaze broke out just before 2 a.m. in the 6700 block of South Park, a terrifying wake-up call for the many residents who said they awoke to the sound of fire alarms and smoke in their homes.

No injuries were reported and the cause of the fire remained under investigation Wednesday morning. 

After residents cleared the building, one firefighter ran back into the building to rescue a cat. Scared, but otherwise unharmed, the animal had been separated from his owner in the chaos. 

The Westmont Police Department is being credited for helping many people to safety.
