CHICAGO (CBS) — Fire Department officials said it appears a grilling accident caused a smoky fire on the upper floors of a high-rise condo building Friday afternoon in the River North neighborhood.

The fire started around 3 p.m. on the balcony on the 34th floor at 545 N. Dearborn St., according to the Fire Department. The fire created a large column of black smoke.

The fire wax extinguished by about 3:20 p.m.

Fire officials said the fire was contained to the balcony, and appeared to be the result of a grilling accident.

Because the fire happened in a skyscraper, it prompted a massive response from the Fire Department, due to the extra challenges posed by fires in high-rise buildings.

“I don’t think I’ve seen this many fire trucks and ambulances, and this much commotion going on just for a fire,” witness Amberly Sowder said.

No injuries were reported.
