"This was a lot more involved than the first fire," Deputy Fire Chief Anthony Giampietro told Boston25. "We had heavy fire on arrival, it had a pretty good head start on us."

The firefighter got injured after a window exploded and chards of glass injured the hand. He was taken to the hospital for stitches.

The cause of the fire is being investigated. But the building is uninhabitable and needs to be torn down. The Red Cross is assisting displaced families.
