Police officers who prove themselves in investigative assignments may be promoted to the rank of detective. In New York City, an investigator starts out as a detective third grade. Subsequent promotions to second and then first grade are based on experience and accomplishments. Detective, who work in plainclothes, investigate crimes and incidents. They interview victims and witnesses, collect evidence and interrogate suspects in a continual effort to solve crimes and arrest perpetrators.
Detectives also work to locate missing persons and recover stolen property.
Investigators may be assigned to precinct detective squads or one of dozens of specialized investigative units that have borough or citywide jurisdiction. No, other large bureaus and divisions within the police department also field detectives. Notable examples are the Internal Affairs Bureau and the Organized Crime Control Bureau, which oversees the narcotics, vice enforcement and auto crime divisions. Call the assigned detective. If you are unable to reach that person after several attempts and he or she does not return your call, ask to speak to the squad supervisor.
