A new lawsuit has been filed against the South Carolina police officer who is currently facing murder charges for fatally shooting an unarmed black man in the back earlier this month.

In the lawsuit, a man named Julius Garnett Wilson, 35, accuses Officer Michael Slager of police abuse for using his Taser on him while he was already laying face-down on the ground during an arrest. The suit also names two other patrolmen who were present during Wilson's arrest, along with the city of North Charleston, the police department and police chief Eddie Driggers, reports Yahoo! News.

According to Wilson, the alleged abuse was capture on a police dashboard video camera, which has since been released to the public. In the video, Officer Brad Woods is seen stopping Wilson for a bad brake light while he was on his way to work about 4 a.m. on Aug. 25, 2014.

Wilson says that he handed Woods a valid Georgia driver's license, but that the officer called for backup while checking his background.

About 10 minutes later, both Officer Slager and Woods approached Wilson and asked him to step out of the car to discuss his suspended driver's license. However, Wilson said he refused because he had a valid license.

When Wilson didn't comply, Woods told the driver he was under arrest without explaining why.

"What am I being put under arrest for, officer?" he asked as the patrolmen began to physically pull him out of the car.

A struggle then ensued and Slager yelled that Wilson was reaching for something in the car. As a result, Woods drew his gun and pointed it at Wilson for a few seconds until Wilson finally let go of the steering wheel and laid face-down on his stomach.

Officer Jerome Clemens then joined to help pin Wilson down with their knees. That's when Slager yells: "Back up. I'm going to tase!"

He then shouts "Taser, Taser" before hitting Wilson in the back.

"Ow! S--t!" Wilson exclaims on the video.

"Turn over or you're going to get it again," Slager says on the video.

On Monday, Wilson and his attorneys held a press conference where he recounted his version of the incident.

"In my lifetime, I have witnessed violent acts by police officers," said Wilson at the conference, according to The Post and Courier. "Without proof of such acts, the word of police officers is always taken over the word of the victims forced to endure their violent acts."

Officer Slager is currently facing murder charges for the killing of Walter Lamar Scott, 50, which was recorded by a bystander. In the video, Scott is seen running for his life while Slager, 33, fires eight shots, fatally striking him in the back.

"The fact that there's a pattern of abuse by this officer gives more credence to the lawsuit than just this isolated event in a vacuum," Wilson's attorney Nick Clekis told the New York Times. "It's not for us being an opportunist. It's that the events have given us an opportunity."
