The young police officer who unknowingly stopped pop star Justin Timberlake for suspected drunk driving earlier this week has been named. According to a prisoner report from Sag Harbor, NY, obtained by the Daily Mail on Saturday, the officer is identified as Michael Arkinson, aged 23. Described as an "over-aggressive" rookie by a Long Island native who had been stopped by him before, the incident has sparked discussions about policing tactics in Sag Harbor.
