A three-year-old child's head was split open after the little girl was violently thrown against a cabinet by her teacher, leaving her sprawled on the classroom floor.

The horrific incident took place in the classroom at Brighter Day Care and Preschool in north St. Louis County, Missouri on Friday February 1, in front of other young preschoolers.

An ambulance was called and the teacher sent the a note to her parents saying 'she fell' as an explanation for the incident.

But surveillance camera footage from the classroom shows the teacher aggressively grab the girl by the arm seemingly without reason as she was standing alone by a chair, drag her, and throw her to the floor.

The teacher sent her home with a note saying 'she fall' but surveillance video footage from her classroom shows the moment the teacher flung the little girl the ground and she hit a cabinet in the process

The child was taken to the hospital in an ambulance and required seven stitches.

Heartbreaking images show how deep the cut was in the child's forehead. It's not clear what the little girl's current condition is.

Now her family, who request to remain anonymous, have hired an attorney to represent them. It's not clear if a lawsuit has officially been filed.

'In no world did this family have any idea that what was called a fall was actually an assault until they came to see that video,' attorney Jennifer Hansen said to Fox2.

'One of the more egregious aspects of this case is that the daycare director told the family that she did not watch the surveillance tape until the family was with her,' she added.

Hansen says five days after the incident a relative of the young child recorded video off of a surveillance monitor with her phone that showed how the young girl was really hurt.

In the video the relative is heard yelping with shock when she realizes the girl was intentionally hurt and her head injury wasn't accidental.

'The daycare could've reviewed that footage at any time. They didn't and they allowed the daycare worker who assaulted this little girl, to continue to work at the facility for five additional days,' lawyer Hansen said.

The teacher involved in the assault was fired immediately after the director saw the video.

Police are also investigating as are state child care inspectors. Inspectors had reported past cases of children getting hurt at that school location.

Now police and state child care inspectors are investigating the incident. Inspectors reveal that two prior complaints had been filed at the daycare preschool center in the past

In one incident from May 2018, inspectors said 'staff did not have a preventative plan in place' when '(one child was) repeatedly hitting and choking another child.'

Back in March 2016, inspectors reported that a 'child fell out of the chair and sustained a left femoral fracture'.

Following the child's injury the attorney for Daycare director Sharon Williams told KTVI: 'All teachers and staff are properly trained and extremely qualified. Providing a quality education in a safe environment is of the utmost importance to our teachers and staff. It has always been our policy to notify the proper authorities and to fully comply with any investigation. We have and will continue to follow said policy.'
