LYNN (CBS) – Lynn Police are warning students not to play a kicking game that has led to criminal charges against at least one student. The game is called “Big Booting.” “One student would walk behind an unsuspecting student and kick them in the back of the head,” says Lynn Police Lt. Chris Kelly. The last incident happened Tuesday. A 15-year old student was sitting in a classroom, when a classmate walked up and kicked him in the back of the head.
