A student attacked her teacher in class at a high school and it was caught on video.
One of the students who witnessed the attack took to Twitter to share videos.
In one video, the student is seen verbally attacking her teacher while putting herself in front of the teacher's face.
The teacher, named Ms. Turner, ignores the student while making a phone call about the girl's behaviour but the girl pushes the teacher's hand, throwing her phone to the ground.
The teacher then leaves the class but the girl goes after her and tries to bang the door behind her.
As the teacher tries to return to the class, the girl physically attacks the teacher and the teacher tries to defend herself by holding the student off.
This soon escalates to a full-blown fight.
Another video shows the teacher and the student fighting on the floor.
It ended with the teacher being carried away on a stretcher after she suffered a broken knee.
The student did not reveal the name of the school.
