NYPD officers are increasing patrols outside a Kingsbridge McDonald’s three days after a 16-year-old boy was shot and killed following an argument inside the fast-food restaurant, police said.

Ring camera video captured the moment gunfire erupted on West 238th Street and Broadway, sending a group of teenagers running in fear. The shooting happened during rush hour, just steps from a busy bus stop.

Police identified the victim as Christopher Redding, 16. Investigators say Redding and the gunman got into an argument inside the nearby McDonald’s before the suspect opened fire about a block away.

Surveillance video shows four suspects – three males and one female – hanging out inside a nearby building before gathering near the bus stop moments before the shooting. Detectives say Christopher was struck along with two other teens, who survived their injuries.

Police were seen patrolling both the McDonald’s and a nearby Wendy’s just steps from the 50th Precinct. Neighbors say the area is known for after-school clashes between teens.

One witness, Victor, says he nearly got caught in the middle of the argument before shots were fired.

“I said don’t beat the guys like that,” Victor said.

The violence has renewed concerns about the location, which neighbors say has been a hotspot for problems for years. In 2016, a McDonald’s manager, Adam Garcia, was fatally stabbed during the night shift.

“I know this area 20-something years — big, big problems,” Victor added.

Police say the four suspects remain at large and are asking anyone with information to come forward.
