A Chicago firefighter is recovering after collapsing at the scene of a fire on the city's North Side. He was battling a fire on the 12th floor of a high rise building at 3950 North Lake Shore Drive Tuesday morning.

His identity hasn't been released but ABC7 has learned he's 50 years old and has been with the department for 30 years. Doctors believe he had a heart attack.

The fire was contained to one unit and may have been caused by a faulty microwave.

No residents were injured but the building had to be ventilated because of smoke.
