Investigators believe a series of early-morning fires at a high school in suburban Philadelphia were arson.
Authorities in Delaware County say the blaze broke out shortly after 4 a.m. Thursday at Penn Wood High School in Lansdowne. No injuries were reported, but officials say the school will be closed Thursday and Friday.
Officials say the fire was first reported in the lobby and spread throughout the first floor. Another fire was reported in a classroom and officials say multiple rooms were damaged.
Lansdowne Fire Company Deputy Chief Wayne Worley says the blaze appears to have been intentionally set and that police found a door pried open.
Investigators are trying to use the school’s security cameras as they search for clues.
