A surveillance camera captured a disturbing and violent school beating at a middle school in Indiana. Now, the teenager and his parents are suing the school district because they say it isn’t doing enough to prevent instances of bullying.

In the video, 13-year-old Austin McDaniel is put into a choke hold and slammed to the ground by a 15-year-old student. The bully then proceeded to punch McDaniel incessantly, delivering dozens of blows until his victim is beaten unconscious.

Students can be seen all around watching the incident, however, no one steps in to help McDaniel — they just watch.
