A pair of NYPD officers who chased down a teen and hit him in the face with a gun — even after he’d​ stopped running and ​had ​raised his hands — have been indicted by a grand jury and will be arraigned Wednesday in Brooklyn Supreme Court, law-enforcement sources told ​The Post.

Police Officers David Afanador and Tyrane Isaac chased Kareem Tribble, 16, after they spotted him peering into the window of a parked van in Bedford​-Stuy​vesant​ on Aug. 29, sources have said.

Tribble tossed the small canvas bag he was carrying and started running when he saw the cops, the sources said.

Surveillance video shows Tribble slowing to a stop and putting up his hands before one of the chasing cops punches him in the face.

After the teen lies down in front of a storefront gate, the other cop slams him in the face with a gun, according to the video and a law-enforcement sources.

The two cops will turn themselves in Wednesday morning and will later be arraigned before Brooklyn Supreme Court Justice Matthew D’Emic, law-enforcement sources said.

An attorney representing Tribble welcomed the charges against Afanador and Isaac.

“What they did was a criminal act and a horrible thing and what’s happening to them right now is well deserved,” said Tribble attorney Amy Rameau, adding that the teen’s teeth were cracked during the assault.

“It was absolutely unwarranted. They had no reason to chase that poor child. They took a look at him and decided they were going to chase him and he got scared and ran.”

Brooklyn District Attorney Ken Thompson is also probing two other taped incidents that appear to show NYPD cops acting improperly.

Meanwhile, a Staten Island grand jury is still reviewing evidence in Eric Garner’s July 17 death, which the Medical Examiner’s Office ruled a homicide caused by an NYPD cop’s “chokehold” as he arrested him for illegally selling loose cigarettes.

A Brooklyn DA spokeswoman declined to comment on the indictment of the two cops.

“Watching the tape was hard. You’re upset, you’re angry,” Tribble’s dad, Thomas Stephens, a 42-year-old truck driver, said in an interview last month.

“The tape speaks for itself. I want to see [justice done].”

The NYPD did not respond to a request for comment. Neither Afanador or Isaac could be reached for comment.

Afanador will face charges of assault, criminal possession of a weapon, and official misconduct – with the weapons rap coming because he hit Tribble with a loaded gun, a law-enforcement source said.

Isaac will be charged with assault and official misconduct.
