NEW YORK – A New York City police officer suspended from duty after he was recorded Sunday putting a man in what the police commissioner said was a banned chokehold could face criminal charges for the second time in his career.Queens prosecutors said Monday they've opened an investigation into Officer David Afanador's actions on the boardwalk at Rockaway Beach, adding that “there must be zero tolerance for police misconduct.”Afanador was acquitted in a previous case stemming from allegations he pistol-whipped a teenage suspect in Brooklyn and broke two of his teeth.The police department moved quickly to suspend Afanador without pay after Sunday’s confrontation.
