VIDEO: Flames erupted from a restaurant in Torrington on Thursday morning.
The fire was reported at Marino's Restaurant on Pinewoods Road, near Winsted Road, around 9 a.m.
When fire crews arrived, they witnessed flames shooting through the roof. At that point, the fire reached a second alarm, they said.
They had to fight it defensively because of a partial roof collapse.
Battalion Chief David Casper said a firefighter suffered minor injuries in the fight.
One person, the building owner, was inside the building but made it safely outside.
Casper said the building was heavily damaged and he wasn't sure how much of it could be saved.
"The extent of the building damage was pretty sufficient that I don't know there is anything that we can save beyond this," he said.
