A fifteen year-old girl has been charged with Arson relating to a fire at the Walmart in Alliston.

Just before midnight on Friday OPP were called to the Walmart on Dunham Drive in Alliston for a fire.

Crews found the fire in the central part of the large commercial building and put it out. Investigators from the Office of the Fire Marshall and members of the OPP Forensic Identification Unit were called in.

Police say Walmart employees were able to identify the suspect who started the fire, which led to the Arson charge for the teenager.

She has been released on a Promise to Appear and will attend court at a later date.

The Walmart will remain closed for an undetermined amount of time.
