A four-alarm blaze that ravaged a Bridgewater neighborhood Tuesday morning was deliberately set inside a vacant building, authorities said.
Bridgewater Fire Chief George W. Rogers said that the fire started in a vacant 10-family building at 76-78 Broad St. and then spread to neighboring properties.
State Fire Marshal Stephen D. Coan’s office said the fire eventually destroyed or damaged six buildings, including three occupied residential buildings.
The fire at 76-78 Broad was intentionally set, according to Coan’s office. That building was totally destroyed, officials said.
Rogers said his firefighters encountered heavy fire upon arrival, and it took firefighters from 10 communities to battle the blaze. A Bridgewater firefighter sustained a minor injury and was sent to Brockton Hospital.
Firefighters had responded to the 10-family unit two weeks ago to deal with several small fires, Rogers said.
The investigation is ongoing.
