Prince George's County, Maryland, police have charged school bus aide DeQuan Brooks with second-degree child abuse and second-degree assault for assaulting a 7-year-old special needs student. The school system has also reassigned the driver of the bus and another adult who was on the bus. Police say the three adults told them the student had acted out and tried to throw Brooks' cellphone out a window. But when they reviewed security video from the bus, police found no evidence to support that story. Instead, they say, the video showed Brooks grabbing the boy and shoving him into the seats.
