The U.S. Justice Department and the FBI will both conduct investigations into a violent episode involving a white South Carolina police officer and a black female high school student, whom he slammed to the ground in a dispute that apparently began over her cellphone.

The incident was captured on video and quickly went viral, the New York Daily News reports. Richland County Sheriff's Office Deputy Ben Fields has now been removed from Spring Valley High School and placed on administrative duty.

Reports are the incident is not the first time Fields has been involved in a physical situation with a student, and he is known throughout the school by students as "The Incredible Hulk" because of his massive build.

Richland County Sheriff Leon Lott openly admitted the video involving his officer looks "disturbing" and added his department plans to fully cooperate with both investigations.

The incident reportedly unfolded after a teacher spotted the still-unidentified victim with her phone out and demanded she hand it over. After the teen refused to give up her phone, Fields was summoned and things quickly turned violent.

"She really hadn't done anything wrong," said Tony Robinson Jr., the student who recorded the video on his cellphone. "She said she took her phone out, but it was only for a quick second."

It appears it only took about that same amount of time for Fields to flip over a desk and slam the silent student to the ground, before dragging her across the room and cuffing her.

"I've never seen anything so nasty looking, so sick to the point that other students are turning away," Robinson added. "They're just scared for their lives. That's supposed to be someone that's going to protect us. Not somebody to be scared of."

As another student can be heard sobbing in the video, Fields says, "I'll put you in jail next."

Indeed, the crying student was taken into custody on charges of disrupting school and required to post a $1,000 bond before being released.

An 11-year veteran of the department, Fields has been assigned to the school as a resource officer since 2008. Over his career, he has been named in at least two different lawsuits, one of them alleging racial bias that is expected to go to trail sometime next year.

Fields also patrols the nearby Lonnie B. Nelson Elementary School.
