Investigators are looking for the cause of a fire that heavily damaged a home on Youngstown’s East Side and injured one firefighter.

Crews from several fire stations were dispatched to a home on the 2000 block of McClure Avenue at around 2:15 a.m. Wednesday where they found flames coming through the roof.

The fire had spread through the attic of the home and power lines had fallen into the yard.

One firefighter was treated for burns to the leg.
