A 9-year-old boy kicks one of the little girls while a daycare worker looks out the window.
The above surveillance video (click on the officer's picture to watch), from Kiddie City Childcare Center in Vicksburg, Mississippi shows a 9-year-old's reign of terror over a room of infants.
The boy can be seen punching one little girl multiple times, then choking another, then patting her back as she cries in pain.
Later he violently shakes another child.
In one instance, you can see the boy kick one of the little girls while a daycare worker looks out the window.
Later the boy picks up the girl and kicks her again.
The 9-year-old can be seen waiting until workers turn away to attack the girls.
Vicksburg police have arrested former daycare worker Sandra Trevillion.
She's charged with two counts of contributing to the neglect of a minor.
"This 9-year-old child, he was allowed to pretty much run rough shot over that entire room for a period of 15 to 20 minutes. All his actions went unnoticed," says Vicksburg Police Chief Walter Armstrong.
The parent of one of the girls, Jamie Williams, 29, says his daughter came home for about a week with injuries, including a busted lip and a bite mark on her chin.
"Don't nobody know nothing at the daycare. Nobody know nothing," said Williams.
Williams said Thursday he got upset when daycare workers couldn't give an explanation as to why his 1-year-old daughter was injured at the daycare Monday.
That's when he slapped the child he thought was responsible.
Police say it was the wrong kid, and Williams was later arrested and charged with simple assault, a misdemeanor.
"I understand why Jamie Williams would be upset. However, even if he had attacked the nine year-old he still would have been arrested and it would have been just as wrong as him attacking the six year-old," says Armstrong.
Police have interviewed the 9-year-old boy and his mother.
It's unclear if they'll face charges.
Trevillion was being held on a $2,656 bond Friday evening.
Williams' court date is set for later this month.
The Department of Human Services is also investigating the incidents and other charges could be filed.
