Two New York Police officers caught on surveillance tape are being investigated for punching and using a gun to bash an African-American teenager.

The surveillance footage, obtained and first reported by "On The Inside" DNAinfo New York, shows a teenager, Kahreem Tribble, being punched and pistol-whipped by two officers. The incident occurred Aug. 29.

The video shows Tribble, 16, running, then stopping, as a police officer approaches him and throws a punch to his face.

The boy raises his hands. The one of the policemen pushes him against a storefront gate when a second officer arrives with his gun pointed at Tribble. Then the officer beats him with the gun around the head before returning it to his holster.

Later in the video an officer retrieves a bag the teenager had on him. A third office arrives, while the remaining officer punches Tribble again, pushes him on his stomach and handcuffs him.

The video ends with the returning officer waving the bag in front of the suspect's face and smacking him with it as a third officer comes up.

The officers from the 79th Precinct in Bedford Stuyvesant, Brooklyn, are at the center of criminal investigation by the NYPD's Internal Affairs Bureau and Brooklyn District Attorney Kenneth Thompson.

"What's depicted on this video is troubling and warrants a thorough investigation," Brooklyn DA Kenneth Thompson told DNAinfo.

Tribble was arrested for possessing 17 small bags of marijuana and disorderly conduct, according to court records. He appeared in court with cracked teeth and bruises, and pleaded guilty to the violation. His lawyer, Amy Rameau told DNAinfo that she plans to file a federal civil rights lawsuit against the officers and the NYPD.

"These police officers behaved themselves in a truly deplorable manner. This type of conduct should not be tolerated, and I want to see them prosecuted for what they did to my client," said Rameau.

Talking to reporters on Tuesday, Mayor Bill de Blasio said: "Clearly, Commissioner Bratton has seen the video and reacted very aggressively in the sense of saying there have to be consequences when anything is done the wrong way. I see these videos as another piece of information that we need to use to improve the relationship between police and community and in many cases to heal the relationship between police and community."

Police claim they thought the teen had a gun. One officer has been suspended without pay during the investigation, and the other officer stripped of his badge and gun and placed on modified duty, Rawstory.com reported.

The New York Daily News is reporting a grand jury may be called as early as next week to investigate whether charges be brought against the officers.

The latest videotaped is the latest video to surface showing abuse in recent weeks. The Internal Affairs Bureau is investigating two separate incidents in Sunset Park, Brooklyn. In one incident, police were accused of tackling a pregnant woman and then shoving a second woman.

The grand jury in Staten Island is still investigating whether to indict the officers involved in the chokehold death of Eric Garner on July 19 Garner's family, meanwhile, have sued New York City for $75 million.
