House of Pizza Fire 

Due to the extensive damage, fire investigators say heavy equipment may have to be brought in to move the mess to help determine what started the fire.

Fire crews were called to the House of Pizza on Main Street, just before 11 o’clock Tuesday night. Someone passing by noticed the flames and called authorities.

Norridgewock firefighters were helped by their colleagues from Skowhegan, Smithfield, and Madison.

No one was inside the restaurant at the time.
