Authorities say someone set fire to Penn Wood High School's Green Avenue campus last month, damaging the lobby and several classrooms. Investigators say they're looking for several individuals believed to be involved.
The Delaware County Daily Times reports that on Thursday the Citizens Crime Commission announced it was adding $3,000 to the reward fund for information leading to an arrest. That's raised the total to $18,000.
The school has had to be closed for the remainder of the school year while repairs are made. Students are attending split classes at another building.
