A Gwinnett County prosecutor is facing charges of felony racketeering and misdemeanor pandering related to a raid on a Dunwoody apartment at the center of an investigation into a purported prostitution ring.

Senior Assistant District Attorney Christopher Quinn turned himself in to Dunwoody police on Tuesday in an expanding prostitution sting that began with a Dec. 29 raid at the Perimeter Center East Apartments, in which seven other people were arrested on charges including prostitution, pandering and racketeering.
