Cops are on the lookout for a suspected gunman who shot up an teenager in Brooklyn earlier this month.


Authorities said the 18-year-old shooting victim was inside a store at 2919 Surf Ave when at least one gunman fired into the building in Coney Island.


Surveillance video from the scene shows the two men walking up to the building. They open the door and both take aim before shooting the victim and taking off.


Cops said they have no motive as of Friday afternoon.


The victim was shot in his leg and hip. Paramedics rushed him to the Lutheran Medical Center, where police said he was listed in serious but stable condition.


Investigators tracked down down one of the shooters, who was identified as Luis Cintron, 23. He was arrested and charged with assault in the first degree.

The second assailant remains at large. He is described as a Hispanic man last seen wearing a black jacket and light-colored sweatpants.

NYPD asks that anyone with information about the shooting or suspect call Crime Stoppers at 1(800) 577-TIPS (8477), or text their tips to CRIMES (274637), then enter TIP577.
