"I've never seen anything so nasty looking, so sick to the point that you know, other students are turning away, don't know what to do, and are just scared for their lives," said Tony Robinson Jr., who made the longer recording. "That's supposed to be somebody that's going to protect us. Not somebody that we need to be scare off, or afraid."
"That was wrong. There was no justifiable reason for why he did that to that girl," Robinson added.
Robinson claimed Officer Fields escalated the incident unnecessarily. At first, Robinson said he told the girl, "you will move, you will move."
"She said, 'No, I have not done anything wrong," according to Robinson. "Then he said, 'I'm going to treat you fairly.' And she said, 'I don't even know who you are.' And that is where it started right there."
Moments later, things turned physical.
Another student taken into custody, Niya Kenny, 18, told WLTX, "I was screaming, 'What the f, what the f is this really happening?' I was praying out loud for the girl. I just couldn't believe this was happening I was just crying and he said, 'Since you have so much to say, you are coming, too.' I just put my hands behind my back."
Kenny was charged with disturbing schools, the station reports.
Her mother, Doris Kenny, asked, "Who was really disturbing schools? Was it my daughter or the officer who came in to the classroom and did that to the young girl?"
Sheriff Lott told multiple media outlets the video shows the officer removing a student who was disruptive and refusing to leave class. "The video then shows the student resisting and being arrested" by the officer, Lott said.
But late Monday night, Lott told WLTX, "It's very disturbing what happened today. It's something I have to deal with and that's what we're going to be doing."
After watching the video, Lott said, he was left asking, "Why?"
"I shake my head and just say ... I ask why, and that's what I want to know. I want to know why something like that happened," he said.
Lott said he is returning home early Tuesday from a conference in Chicago.
Wilson said Lott is asking for public patience during the investigation.
The images captured an "egregious use of force" against the student, ACLU of South Carolina Executive Director Victoria Middleton said.
