Grand Rapids TV stations WOOD and WZZM reported the video posted online shows a Whitehall High School student being beaten. The bus driver yelled to try to stop the attack, and pulled the bus over and called 911 to report the attack.
The Muskegon County Sheriff's Department is investigating and says it plans to seek assault charges against the two boys in juvenile court.
Whitehall school officials said what happened on the bus is unacceptable. School punishment is also expected.
