The roof of a building collapsed early Friday during an extra-alarm fire in the Marquette Park neighborhood on the Southwest Side.

At 12:41 a.m., fire crews responded to the two-alarm blaze at a two-story building in the 2900 block of West 63rd Street, according to a tweet from Chicago Fire Media Affairs. The building consists of an unused first-floor storefront and apartments on the second floor.

The fire tore through the building’s roof, causing it to collapse, Chicago Fire Media said.

The blaze was struck out by 2:10 a.m, but fire crews have not conducted a search of the building due to heavy fire and the instability of the structure, Chicago Fire Media said.
