Tony Robinson Jr. spoke exclusively with News19 Monday night about what happened between a student and an officer. A video that he took shows the officer forcibly removing a student from her chair, dragging her several feet, then handcuffing her.   

"It was definitely a scary experience," he said. 

Robinson says he went into the morning thinking it would be a normal, routine day of school. He was in math class, and he and his classmates were working on their assignments. 

Around 10:30 a.m., the girl who had the confrontation with the officer was working on her computer, and had her phone out, Robinson said. He said the teacher asked her for her phone, but she said no. An administrator was then called to the room, and Robinson said he pleaded with the girl to get out of her seat, but she didn't.

"She really hadn't done anything wrong," Robinson said. "She said that she had took her phone out, but it was only for a quick second."

While she didn't comply, Robinson said the girl was apologetic.

Then the officer, identified as Ben Fields, was called to the class. Robinson said when Fields came in, he asked Robinson's friend to move a desk. According to the student, Fields then shut the girl's computer, and moved it to another desk. 

Robinson felt something was wrong, and pulled out his phone and began recording. 

"When I saw what was about to happen my immediate first thing to think is let me get this on camera. This is going to be something that not only I'm I going to be like 'wow did this really happened at my class' but just something that everybody else needs to see. This is something that we can't let this just pass by.

The officer then began speaking with the student. 

"He asked her again, 'will you move, will you move.'  She said 'no I have not done anything wrong.; 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. 

"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," Robinson said. "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."

Fields is on administrative leave, and is currently not working in any capacity for the department. Richland County Sheriff Leon Lott said he was cutting short a business trip to Chicago to deal with the matter Tuesday.
