There were ten people displaced–eight adults and two children.

“Red Cross was on scene, and we got assistance from the MBTA, housed them in an MBTA bus due to the cold weather concerns,” Masucci said.

Damage from the fire was estimated at around $150,000-$200,000.

The cause of the fire was still under investigation.
