A mother is suing a daycare centre after footage captured teachers encouraging preschool children to fight.
Nicole Merseal has accused the teachers of organising a fight-club inside a Missouri daycare in 2016.
The mother says her then 4-year-old son was encouraged to fight another child, claiming teachers Mickala Guliford and Tena Dailey permitted another child to "intimidate and harm" her son.
Speaking to ABC news, Merseal said her son was "afraid" and couldn't understand why his friends wanted to "beat him up".
"My son was very afraid," Merseal told ABC News. "He didn't understand why his best friends beat him up. These are children that he's been around for a couple years. He described them as his best friends. He just doesn't understand why they punched him in the face. ... I don't know any parent that could watch their children go through this and not be upset."
