Fire rips through 4-story building in Cambridge

CAMBRIDGE -- Flames erupted at a four-story building on Hancock Street Saturday evening.

The fire spanned multiple floors of the brick building that is part office space and part residential.

"There were about 20-foot flames coming out of the windows on about a quarter of the building and there was a lot of smoke.  I've never seen anything like it in my life," one witness told 7News.

Crews were able to put the fire out and no injuries were reported.

Investigators are trying to determine what sparked the flames.
