GLENDALE, Ariz. -- Investigators are trying to figure out the cause of a fire at a Glendale elementary school.
KTVK-TV reports that the blaze began Friday afternoon at Glenn Burton Elementary School inside storage sheds.
Authorities say the fire quickly spread to the attic of a classroom.
They say firefighters who happened to be in the vicinity spotted smoke and followed it to the school.
Crews managed to keep the fire from spreading to the main campus building.
School supplies inside the sheds were destroyed.
