Students recorded this video on campus Friday. Round Rock police say the student was taken into custody for an incident that happened before she was slammed to the ground.
A second video, also shared online, shows that same student attacking another girl before an assistant principal stepped in and stopped it.
The school's principal released a statement saying, "My administrative team, along with district leaders, is working with Round Rock police to fully review the situation, what led up to it and how it was handled."
