RUTHERFORD — A 16-year-old girl from Paterson suffered serious head injuries after she fell out of the back of a school bus this afternoon, police said.

Lt. John Russo of the Rutherford police said the girl was taken to Hackensack University Medical Center, where she remained in pediatric intensive care of around 7:30 p.m. The girl has not been identified.

The accident occurred at around 3:30 p.m. when the girl was riding aboard a bus for special-needs students. As the bus traveled along Riverside Avenue, she managed to open an emergency door, and fell out.

Russo said the girl is a special-needs student. Russo declined to say what school the bus was serving, but confirmed that it was not a Rutherford public schools bus.

Detectives have ruled out all criminal activity in the case, and determined that the bus was obeying the posted speed limit of 35 miles per hour at the time of the accident.

"We've ruled out anyone else being involved," he said.
