The NYPD's Civilian Complaint Review Board confirmed Tuesday that the screaming plain-clothed man is an NYPD officer. The passenger who filmed the encounter said: "Our Uber driver, Humayun, was abused by a police officer today in New York. The rage, door slamming, throwing items into the car, threatening arrest without cause was bad enough -- but the officer's remarks at the end really took it to another level."
