The officer, Michael Daragjati, 32, who prosecutors said was recorded using a racial slur to brag about the arrest, was also charged with making a death threat, extortion and fraud in separate episodes.
Officer Daragjati, who is white, was charged in an indictment unsealed in Federal District Court in Brooklyn. The officer, who wears civilian clothes and drives an unmarked police vehicle, came across the black man on Targee Street in the Stapleton neighborhood of Staten Island on April 15 and decided to stop and frisk him.
