WARREN, Ohio (WKBN) – Fire officials believe a fire in an unoccupied portion of a plaza in Warren is suspicious.

Warren firefighters were called to the Jamestown Village Plaza around 11:40 a.m. Tuesday. The fire was located in a separate building across from the parking lot from Giant Eagle.

When they arrived, they said they found a mattress burning up against the building.

Firefighters found a similar scene last night, too, when a mattress was also found burning next to the building.

Due to the circumstances, firefighters say they believe the fire is suspicious.
