WPVI-TV(LANCASTER, Pa.) — Police near Lancaster, Pennsylvania, are searching for a driver who authorities say caused a school bus to crash Wednesday morning, sending 15 students and the bus driver to the hospital.

Police said a driver in a sedan hit the back of an escort vehicle in East Lampeter Township. The escort vehicle was then pushed into another lane, side-swiping the school bus.

The collision tipped the bus on to its side and trapped one student underneath; the student was transported to the hospital via helicopter, police said.

Fifteen students and the school bus driver were hospitalized, a Lancaster General Hospital spokesperson said. Three of the students were admitted to the trauma unit. All other injuries were considered minor, a hospital spokesperson said, and five students have since been released.

Police are looking for a late model, white sedan with front-end damage in connection with the crash. The driver was last seen heading east on Route 30, police said.

The students were from the Lancaster Mennonite School, police said.

East Lampeter Township is about 65 miles west of Philadelphia.
