Two teenagers vandalized three buses parked behind the York Learning Center in North York on Sunday, police said.

A witness told officers he saw two teenage boys committing mischief about 5:10 p.m. at the 300 E. Seventh Ave. school, and that the youths took off when he startled them, according to Northern York County Regional Police. They were last seen running northbound along the Codorus Creek.

Police found motor oil and other vehicle fluids dumped on the floor of one of the buses, and the teens emptied a fire extinguisher in two other buses, police said.

Anyone with information about the teens' identities or the vandalism is asked to call police at 292-3647, or leave a tip online at
