A large fire sent a massive plume of smoke into the sky in Chicago during the Tuesday afternoon rush hour.

The flames were seen around 4:30 p.m. in the 5000 block of Troy, near North Park University in Chicago's Albany Park neighborhood.

Video footage from NBC Chicago's Sky 5 helicopter showed large flames shooting out of what appeared to be a three-story building, with the flames possibly spreading to another building nearby.

Further details on the fire, including whether or not anyone was inside the building, remained unclear.
