After a brief physical altercation with the sergeant, the subject was able to flee with his accomplice in a silver Ford Fusion. The fleeing vehicle was spotted Detectives from the Robbery Intervention Detail (RID) that were responding to the area. As the subjects fled, they fired on a RID detective striking his vehicle.
