Lincoln Park Fire: Building Collapses In Extra-Alarm Fire (VIDEO)

A three-story brick home dating back to 1888 collapsed during an extra-alarm fire in Chicago's Lincoln Park neighborhood Friday afternoon.

The fire on the second floor of a vacant building, located at 525 W. Armitage Ave., was first reported at 12:50 p.m., and was later upgraded to a two-alarm fire after it began to engulf the structure, CBS Chicago reports. About an hour into the blaze, at 1:55 p.m., the building collapsed. The fire was reportedly extinguished by 2:15 p.m.

The blaze required some 100 firefighters to put it out and, meanwhile, smoke from the fire could be seen as far away from the fire as the Loop, according to NBC Chicago. No injuries we were reported as streets surrounding the building had been blocked off before it collapsed.

The building, which used to house rental units, was in the process of being rehabbed before the Friday fire, according to Fox Chicago.

It remains unclear at this time what caused the fire.
