Chicago firefighters have controlled an extra alarm fire on the city’s North Side. Large plumes of black smoke could be seen from downtown Friday afternoon as Chicago firefighters battled the blaze at 525 W. Armitage, a residential building in the city’s Lincoln Park neighborhood. The three-story building was consumed by the flames, causing it to collapse.

Fire officials said the call came in just before 1:00 on Friday, and firefighters were able to knock it down a little over an hour later. As of late Friday afternoon, firefighters were still on scene.

A spokesman for the fire department said the building was vacant, and that nobody was injured in the blaze.

Earlier, sources had said there were two structures involved in the fire, but a spokesman later confirmed the flames were confined to just a single structure. He said approximately 100 firemen were on scene to battle the blaze and they used around 40 pieces of equiptment.
