A school bus driver is facing multiple charges after the bus he left unattended drifted across a road and struck a child Monday morning in Beltsville, Md.
Four other students on the bus were also transported to the hospital with minor injuries.
The driver, 61-year-old Arturo Roberto Harris, has been charged with reckless endangerment, leaving a child unattended, and several traffic charges related to the accident.
Police spokeswoman Officer Nicole Hubbard said the driver left the bus running while it was carrying elementary and middle school-aged children in front of High Point High School around 7:30 a.m.
"Preliminarily, we believe the bus driver left the students unattended on the bus, and then for reasons which remain unclear, the bus started drifting and drifted across Powder Mill Road," Hubbard said.
The bus then hit an elementary school-aged boy waiting at a bus stop.
The child was sitting on the curb with several others when he was hit. He was pulled from underneath the bus by a bystander, News4's Richard Jordan reported.
All five children have been released from the hospital.
