A VIDEO which purports to depict a plainclothes police officer slapping a man and then taking him away in a marked police car has evoked the ire of National Security Minister Jack Warner.

Warner has now called on acting Police Commissioner Stephen Williams to investigate the situation.

The 57-second video entitled "Police independence brutality" was posted on the CCN TV6 U-Report four days ago by someone using the name isiahblaxx.

The description which accompanies the video states "as we celebrate our 50th anniversary, we still see police brutality eminent in our society".

The video has gone viral on social networking site Facebook with more than 16,600 views.

The video begins with a man dressed in a white jersey and blue jeans, who is purportedly a police officer, standing near the open driver's side back door of a marked police car.

A uniformed police officer is standing behind the plainclothes officer.

People are heard quarreling with the officers.

The plainclothes officer then turns around and walks to a man wearing a rasta hairstyle and says: "What you tell me? I is an idiot, that's what you tell me, I is an idiot."

The plainclothes officer then attempts to grab the man's right wrist.

"You hear me say that? What you holding me for?" the man is heard saying as he pulls his hand away. The plainclothes officer then hits the man a slap across the face and says "not me eh".

The man is then held by the two officers and escorted to the back passenger seat of the police car.

The two officers enter the police car, with the uniformed officer taking the driver's seat.

People are heard voicing their shock at the incident.

The police car reverses from the area where it was parked.

Warner, speaking to members of the media, following a visit to West Shore Medical on Western Main Road, Cocorite yesterday, said he had seen the video.
