OROVILLE, Calif. -

An Oroville school is being forced to cancel classes for a second day Wednesday after a fire overnight Monday did hundreds of thousands of dollars in damage to the building.

The fire was reported around 1:23 a.m. after what's thought to be an electrical fire started somewhere in the ceiling.

Fire crews from four agencies, including CAL FIRE Butte County rushed to the scene and were able to keep the fire from destroying the building.

On Tuesday morning, disaster cleanup crews were on site vacuuming up water, soot and other debris. They'll also work to remove smoke damage inside.

Outside, caution tape kept teachers and students from entering the building, with classes canceled for the day Tuesday.

Oroville City Elementary School District Superintendent Dr. Penny Chennell says she got the call about the fire about 2:45 a.m.

"My immediate thoughts are, 'Arson, oh my god, what's happening,'" Chennell said. "It looks as though it may have been something electrical, but the school will not be able to be used for the rest of the school year. We have another elementary school located behind Sierra Del Oro and so the children will hopefully have classes within the next two days."

That school, Wyandotte Avenue Elementary School, will be ready to accept Sierra Del Oro School students on their grounds on Thursday.

And with summer break set to begin at the end of next week, it appears as if the disruption will only last about a week and a half.

Chennell says the damages will be covered by insurance and that they hope to get work started as soon as possible so the building will be ready to open at the beginning of the next school year.
