The cellphone video shows one student repeatedly shoving another student as he tries to walk away. The video was recorded on Friday at Cajon High School.
Students told Eyewitness News on Monday that the video has been the subject of talk around campus.
"I thought it was very sad that he was going up to him and bullying him, trying to fight him. I thought it was very brave of the other kid to walk away and try to avoid it," said Angelique Escamilla, a freshman.
"I don't know how somebody could really bully somebody like that. If a person doesn't want to fight, then they don't want to fight," said Kiyhana Bluitt, a junior.
"I thought that was scandalous what he did. I didn't think that was cool," said Justin Sunlar, a sophomore.
The student seen walking away is shoved, hit and eventually punched in the back of the head. Afterward, the student seen pushing the victim posted the video to his Facebook account. That got the attention of San Bernardino City Unified School District administrators and school police.
"School staff and district police worked hand in hand and were able to identify the student who was the aggressor as well as the student who was the victim, and an arrest was made on Saturday," said Linda Bardere, spokeswoman for the school district.
The student is now at juvenile hall and facing two misdemeanor charges. Another student heard in the background egging on the assault was also ticketed.
While many witnessed the incident, one student stepped in to help the victim.
"One young man went up and walked the victim away to safety. The one thing they fell short on was reporting this to a trusted adult," said Bardere
School officials tell us once the student is released from juvenile hall, he will be facing disciplinary action at the high school.
