UNITED STATES – A high school girl attacked a classmate violently, punching her in the head over 30 times while her classmates looked on and laughed.

The horrific footage of the assault, which occurred at a Nevada high school in Las Vegas, shows the victim raising her hands to defend herself before resting her head on her desk as the attacker continues to pound her in the head.

As the attack continues, the teacher, extends arms to the attacker and yells: ‘Stop, stop, stop. Get off of her’
