Two videos titled "Kiddie Fight Club" were sent to KVUE in Austin, allegedly showing the fights at The Greenwood School.
One parent told the station the preschool director and a teacher paired children, put them inside the circle and allowed them to fight.

The director sent a letter to parents, admitting it was a mistake.
She said she allowed a little bit of shoving and what she called "shirt slapping" because she was trying to "un-teach" that fighting is a fun game and that hurting others is okay.
The videos have now led to a state investigation.
