FALL RIVER, Mass. (WPRI) – Firefighters in Fall River battled a large fire in the city Sunday afternoon.

The initial reports came from a vacant triple-Decker at 169 County Street at about 11:30 in the morning.

Firefighters at the scene tell Eyewitness News that the vacant home caught fire and was heavily damaged.

“Upon arrival, crews had heavy fire in the third floor and attic area, and heavy smoke from the roof line,” Fall River Fire’s Acting District Chief Matt Johnson tells Eyewitness News at the scene.

One neighbor suffered minor smoke inhalation but was treated for their injury and released.

Crews were on scene for hours in the summer heat, which didn’t make fighting the blaze any easier.

There was a fire at the same house in late March, which went to three alarms and displaced six families, although there were no injuries reported.

“We had top force entry,” says Acting Chief Johnson. “This building had been previously boarded up” from the fire four months ago.

Fire officials say the home has been vacant since the first fire in March.

Acting Chief Johnson tells Eyewitness News at the scene it’s possible the fire started outside of the home, but didn’t go so far as to speculate if it was intentionally set.

“We have investigators on the scene, the Fall River Fire Department, the Fall River Police Department, and the State Fire Marshal’s Office are here,” says Acting Chief Johnston. “The active investigation is underway.”

The fire Sunday is now under investigation.
