Tuesday, Darlington police released a video showing a teacher's aid and a behavioral manager at St. John's Elementary hitting a 10-year-old special needs student on a bus.
The women were yelling at him to hush as they tried to put a safety harness on the child.
In the video, you can clearly see the boy being slapped in his face and pushed.
At one point, you can hear the 10-year-old crying.
The images of the other students are blurred, but the 10-year-old's mother signed a release saying her son's face could be shown in the video.
Tomeka Self and Rosanna Dudley were arrested last Friday on charges of simple assault and battery.
The boy is not able to communicate verbally, and police say he was not aggressive at all toward the women.
Officers say they've pulled all available video from that school bus and found no other such incidents.
The employees are on administrative leave without pay pending the outcome of the investigation.
They are set to appear in court May 9th.
