Delaware police released video footage on Thursday of a white officer kicking a black man in the face and knocking him unconscious as he appeared to be complying with the cop's orders.

The incident occurred in August 2013 outside of a Hess gas station in Dover, reports The New York Daily News. In the dash cam video, an officer yells "Get on the f***ing ground!" to Lateef Dickerson, who fit the description of a suspect who reportedly had a gun.

Responding to the officers' commands, Dickerson begins to lie face down on the ground. However, Dover Police Cpl. Thomas Webster IV, 41, walks towards him and kicks him in the face.

Dickerson's baseball cap then flies off of his head as he drops onto the asphalt. Dickerson, who was 30 at the time, was left unconscious and taken to the hospital with a broken jaw.

Officials say that no gun was found at the scene. The charges of assault, theft and resisting arrest that were filed against Dickerson were later dropped.

Following the attack, a grand jury failed to indict the 8-year veteran in March 2014 and he returned to full duty in June 2014. The U.S. Attorney's Office also found no civil rights violations.

However, after a new incoming prosecutor decided to reopen the case, a second grand jury indicted him on second-degree assault. As a result, on Monday Webster was arrested and placed on unpaid leave.

According to USA Today, the American Civil Liberties Union (ACLU) is suing the Dover Police Department on behalf of Dickerson.

"We believe that the video demonstrates the need for large-scale reform of the Dover Police Department, specifically improvements to their use of force and internal affairs practices, and supervision of their officers," said Kathleen MacRae, executive director of the ACLU of Delaware.

The video was released after the presiding federal judge in the ACLU case handed down a ruling saying the video was no longer considered confidential. That allowed the police to make it public.

Civil rights leader Jesse Jackson also commented on the Dover incident.

"What is clear is that a man who is down should not be kicked to unconsciousness," he said. "That is excessive force."
