A firefighter suffered an arm injury while battling a two-alarm blaze that tore though a Dedham home late Sunday night, displacing seven people, according to town Fire Chief Bill Spillane.

He said via email that firefighters were called to 99 Oakdale Ave. at 11:33 p.m.

“The fire started on the front porch and extended up the outside of the house and into the attic,” Spillane wrote. “The cause of the fire is still listed as “undetermined” and is being investigated by the State Fire Marshal’s office and the Dedham Fire and Police investigation units. Damages are estimated to be $250,000 - $300,000.”


Spillane also provided an update on the injured firefighter. No civilians were hurt.

“A Dedham Firefighter was transported to the hospital last night for an arm injury and was released late this morning,” Spillane wrote.

He added that there were “seven adults displaced by the fire and they are being assisted by the American Red Cross.”

IAFF Local 1735, the union for Dedham firefighters, said via Facebook that the Quincy, Boston, Needham, and Westwood fire departments helped at the scene, while the Norwood, Milton, and Newton departments provided station coverage during the response.
