An out-of-control student got into a violent confrontation with his teacher after his phone was confiscated during class.
The ninth grade student was in the middle of a lesson being taught by his physics teacher at John F. Kennedy High School in Paterson, New Jersey, when he flew into a rage.
A video, taken by one of the other students, shows the classroom descend into chaos as the 16-year-old boy wrestles his 62-year-old teacher to the floor.
