PHILADELPHIA — The Philadelphia School District and city police are investigating a fight between a student and teacher that was caught on video and posted to Facebook.

Authorities aren’t identifying either person involved in the fight at Lincoln High School on Monday.

Police say they’ve charged the 16-year-old boy, but are not releasing his name because of his age. The teacher’s name hasn’t been released either, but he’s reportedly an English teacher.

Authorities say the boy argued with the teacher about being late to class and that the teacher called for security, but began fighting with the student after the student pushed him.

The video shows the teacher and student punching and kicking one another and the teacher putting the student in a headlock at one point.

The teacher hasn’t been charged.
