Police in Brooklyn Fatally Shoot Man Who Chased and Shot at a Mugger

Four police officers were responding to reports of gunshots in East Flatbush when they saw the man, 20, chasing another man and a woman, the authorities said.

Police officers in Brooklyn shot and killed a 20-year-old man on Monday who had been shooting at a mugger running off with his wallet, according to three law enforcement officials familiar with the matter.

The man, Nathan Scott, was firing at a fleeing man and woman after his wallet was stolen, according to the officials, who spoke on the condition of anonymity because they were discussing a continuing investigation.

The man who stole Mr. Scott’s wallet later confessed to the theft, one of the officials said. Mr. Scott gave chase for several blocks after he was robbed, according to an official.

The fatal shooting occurred after four officers in an unmarked car, responding to calls of gunshots around 6 p.m. at East 57th Street and Linden Boulevard in East Flatbush, came across the foot chase, John Chell, the Police Department’s chief of patrol, said at a news conference on Monday.

The officers saw the man in pursuit of the couple, “firing numerous rounds trying to shoot them,” he said.

Mr. Scott was shot several times by the officers and was taken to Kings County Hospital, where he died, the authorities said. The shooting is under investigation by the Police Department’s Force Investigation Division, which examines officers’ use of deadly force, to determine whether the officers followed proper protocol.

No one has been charged in the incident, the police said. The couple chased by Mr. Scott were not harmed and their names have not been released. None of the officers were shot, the police said.

A gun was recovered at the scene, according to Chief Chell. A 60-year-old man was also shot twice on the street, he said, but it was unclear by whom.

In a porch security-camera video shared on social media and in news reports, two people can be seen running on a sidewalk, while gunshots can be heard in the background and someone yells, “hey, hey, stop, stop.” Shortly after, a man runs into the frame as a gray sedan stops and several shots are fired. The man, possibly Mr. Scott, then collapses.

Four officers can be seen exiting the car, shooting over a dozen times in the man’s direction. While approaching the man, officers yell at him not to move while he is on the ground, and more officers soon arrive at the scene.

The uniformed officers were assigned to the Brooklyn South community response team and were helping officers in the 67th Precinct, Chief Chell said.
