Transcript for Mother sues day care, accuses staff of directing 'fight club'

surfaced showing preschoolers allegedly encouraged to fight one another inside a St. Louis day care. Here's linsey Davis. Reporter: Disturbing questions about this video shows preschoolers at a St. Louis day care fighting, as teachers look on. Caught on camera by a 10-year-old after the family says his little brother was forced to fight, ending up in tears. The mother is now suing, calling that incident, seen here on a day care camera, part of a fight club. I don't know any parent that can watch their children go through this and not be upset. Reporter: One teacher appears to be jumping enthusiastically, as another helps the children put on hulk fists. Nicole Merseal reported the incident back in 2016 and both teachers kwr quickly fired. One teacher told investigators she let the kids fight as a stress release after the day care's heater broke. No one is being held accountable. And if I'm not a voice for my children, who will be? Reporter: David, those two teachers never faced criminal charges. The department of health and senior services tells us they did conduct an investigation and they required the facility to do additional training. David? Linsey Davis, thank you.
