"School resource officers, detectives and school officials are working to find out exactly what happened," the Huntington Police Department said.
The video shows a boy punching another sudent who doesn't appear to fight back. A third boy steps in and punches the attacker, knocking him to the ground.
The student, who is being called a hero by classmates, asks why the attacker was "hitting a blind kid."
According to police, the partially blind student and his attacker knew each other and have a history of not getting along.
“The student who stepped in, his actions were reasonable,” said Officer Jennifer Marlatt of the HBPD.
Police arrested the alleged bully for misdemeanor battery. He was later released to his parents.
The brother of the alleged bully said the student was taunting his brother, and he believes his brother was the victim.
"This so-called hero, he comes up and punches him in the back of the head," he said. "Pretty wrong, if you ask me. He could've killed him."
No arrest is anticipated for the third student who intervened in the fight.
