"Hit her. It's after school, it's after school," the woman can be heard saying in the video. "You can't get in trouble."
The victim's mother says both students go to Turlock Junior High School.
For Acuna, watching the video of her daughter being attacked was bad enough. However, what had her fuming was watching an adult physically restraining her daughter so the other teen could hit her.
Acuna says she's pressing charges against the woman in the video.
The Turlock Unified School District also confirmed that even though the fight happened off campus, the students involved can still be disciplined. The district says they are conducting their own investigation into the fight.
