An Alabama police officer is on leave while authorities investigate a weekend arrest captured on video in Reform showing a handcuffed man being hit with a stun gun.

The video begins with a white female officer ordering the Black man to “stand up” after he was handcuffed in the roadway in Pickens County.

She then tells him to lay down on the front of a vehicle, which he does face down.

The officer then holds a stun gun to the man’s back while she goes through his pockets. She tells him to “stay still” at which point he says, “I ain’t doing shit, bro. I got a gun right there.”

The officer laughs as she retrieves the gun and says, “Oh yea.”

She then deploys the stun gun directly into the man’s back, telling him to “shut the (expletive) up” as he screams.

The man then begins to cry, repeatedly saying, “Oh my God.”

The officer then says, “Do you want it again?” as the man continues to cry. “Shut your bitch ass up,’’ the officer says.

That’s where the video ended. The video has been shared thousands of times.

Reform police Chief Richard Black and Mayor Melody Davis sent out a statement Monday acknowledging they are aware of the video involving a “citizen’s arrest” that took place on Saturday.

“The department is in the process of turning over all materials related to this arrest to the Alabama State Bureau of Investigation and has requested a thorough investigation into the circumstances surrounding the arrest,’’ the statement said.

Police and city officials referred questions about the arrest to 24th Judicial Circuit District Attorney Andy Hamlin.

Hamlin said the man was arrested on a trafficking fentanyl charge. He said more information is expected to be released later today.
