An investigation is underway after a Fall River triple-decker was heavily damaged by fire Monday afternoon.

Fall River District Fire Chief Matt Johnson told 12 News firefighters rushed to the Danforth Street apartment building to find flames shooting from the second and third floors.

Johnson said firefighters had to evacuate the building temporarily and battle the flames from the outside due to the significant amount of fire. The firefighters eventually went back inside to finish the job once the bulk of the fire was knocked down, he added.
