A viral video shows how a Texas junior high school student was violently attacked by another student while adults attempted to intervene halfheartedly. The brutal incident culminated with a head-stomp, clearly depicting the severity of the assault.

The two youngsters involved are Harwood Junior High School students in Bedford, Tx., where the violent incident took place, the school confirmed in a letter, according to WFAA.

Disturbing video of the one-sided incident showed the aggressor sitting on another boy’s chest while he rained down fist after fist on the head of the flailing victim.

At one point in the attack, the victim attempts to get up, but is tackled by the aggressor and brought back down to the concrete of the school’s courtyard.

As he is beaten senseless, the young boy looks to fellow students for help, but instead they make whooping noises, watch, and record on their phones as the boy suffers from punches to his face and back of the head, video showed.

Teachers failed to halt the violence.

Video shows two adult men, one who doesn’t put down his thermos, slowly approach the skirmish and gently pull the attacker off without restraining him.

When the punches subsided, the attacker stands up, unimpeded by the adults, and stomps on the head of the victim, knocking him unconscious and rendering him immobile. 

After the stomp, no one goes up to help the victim for at least 20 seconds, instead, students continue to gawk and adults are nowhere to be seen.

It was unclear how badly injured the student was or if he required medical attention.

The principal of Harwood Junior High School confirmed the viral-fight video occurred at their school and that they were investigating the matter.

“However, I want to emphasize that fighting is a severely inappropriate behavior, and this type of incident is completely unacceptable,” the principal said in a letter to parents, WFAA reported.

“The incident is being taken very seriously, including investigation of the complete sequence of events using video and interviews, surrounding context, actions of additional students and staff, and district processes related to student fights,” the letter read.

The Bedford Police Department investigated the incident and has referred it to the Tarrant County Juvenile Justice System, according to a statement posted on Facebook.
