HERE IS THE GRAPHIC FIGHT VIDEO

The video shows the female student throwing heavy punches at a female substitute teacher. Miami Central Senior High School is one of the lowest-performing schools in the State of Florida.

But the teacher fights back. After surviving the initial attack, the teacher turns the tables on the teen - by grabbing the student’s hair and pushing her head down. Later she places the student in a secure headlock.

While the fight is happening - no student steps in to break it up. Instead, the other students were seen laughing and recording the incident on their own cellphones.
