Butte law enforcement officials are investigating an attempted arson fire at the old Greely School on Silver Bow Boulevard.
The incident occurred Wednesday night around 10 p.m. Three suspects wearing dark colored clothing were seen on the south side of the building. They ran from the area at the time that a witness saw flames shooting up the side of the building.
The suspects were last seen running east and then south from the school. An investigation revealed that the suspects used a Molotov cocktail device which was ignited and thrown against the side of the school.
A second device was recovered near the building but had not been ignited.
The school sustained minor damage.
