The incident occurred around 4:15 a.m. in the area of Nostrand Avenue and St. Johns Place, Police Commissioner Jessica Tisch said at a news conference streamed on Facebook, during which she identified the victim as Detective Robert Carroll of the Sex Offender Monitoring Unit.
An 18-year-old man, who had been captured on camera with a gun in his hand five minutes before the shooting and one block from the scene, approached an unmarked police vehicle, according to Tisch. Officers exited and attempted to engage the armed teen, and three officers discharged their weapons, Tisch said, adding the teen was not struck.
