During the operation, Mr. Duprey sold narcotics to one of the officers. A man, who the police did not identify, then wheeled a motorbike over to Mr. Duprey. Mr. Duprey got on the bike and sped off down Aqueduct Avenue, driving one way then another, the police said. It was then that Sergeant Duran grabbed a white plastic cooler from the table and threw it at Mr. Duprey, the 18-second video clip shows. The cooler struck Mr. Duprey, and the motorbike skidded.
