Once the renter of the motel room lowered the volume of the music and the police declined to issue summonses, the police no longer had any reasonable suspicion that would justify the continued detention of the room’s occupants. Once the noise was abated, the police no longer had an independent basis to detain the occupants, or a basis to run warrant checks on them. Such action was unlawful. And because the detention and warrant checks were unlawful, the subsequent pat-down of Woodard was also improper. The judgment of the Appellate Division is therefore reversed, and the matter is remanded to the trial court for the withdrawal of defendants’ guilty pleas and further proceedings.
