LEWISTON (AP) — Maine investigators say a doughnut machine ended up being the cause of an early morning fire in Lewiston.

LePage Bakery caught fire just after 3 a.m. Monday. Firefighters say a witness reported the fire after seeing flames on the roof of the building.

About 40 employees were inside the building at the time of the fire, but all escaped with no injuries.

Investigators say the accidental fire started in the basement in a doughnut machine, and caused extensive damage to an employee break room.

Officials say food was damaged from smoke and water used to douse the fire, and most of it will have to be thrown away.
