MINNEAPOLIS (WCCO) — Crews battled a fire Wednesday morning at an apartment building in north Minneapolis.

The Minneapolis Fire Department says crews responded to the fire around 8:30 a.m. at a three-and-a-half story, 18-unit apartment building on the 1300 block of Irving Avenue North. Firefighters found flames shooting from the building’s third floor.

Crews quickly knocked down the bulk of the flames inside the apartment unit where the fire started. After, they checked if the fire spread to other nearby units and put out flames in the cockloft.

Extra help was called to search the building and evacuate all the residents.

MFD says one resident suffered minor injuries. They were treated at the scene and released. One firefighter was also treated for overexertion.

The cause of the fire is under investigation. At this point, it is unknown how many of the apartment units are uninhabitable. Red Cross was called for all of the 18 families – 39 people total – until a final determination can be made.
