CHICAGO-- Chicago firefighters have put out a large fire that broke out on the 50th floor of the John Hancock Center.
They called in extra personnel to do a top to bottom search of the building which is now complete.
Five people, including a Chicago Police officer, suffered minor injuries. Firefighters did not order a mandatory evacuation of the building, but some people did evacuate their units on their own.
Fire officials say the unit's owner told them the fire began in a bedroom.
It's not yet clear what started it.
Residents on the 50th floor are not being allowed to return to their homes yet.
