A fire broke out near the top of Trump Tower on Monday, causing smoke to billow out over the skyscrapers of Midtown Manhattan and Central Park.

The New York Police Department said that the small electrical fire had started around 7:20 a.m. in the roof area of the building. Firefighters responded almost immediately and quickly brought the blaze under control.

A tweet from the Fire Department indicated that the fire was in the building’s heating, ventilation and air conditioning system.

Trump Tower has two roofs, a low roof that houses mechanical equipment and a higher roof that covers the equipment. A fire official said that there was no fire in the building and that firefighters were able to extinguish it using water despite the cold weather.
