Powers and authority

Members of New York city law enforcement agencies receive their powers and authority from New York State Criminal Procedure Law as listed:

List of Agencies

Since 1942, correction and probation services have been handled by separate agencies, not the sheriff's office. The New York City Marshals, who are independent public officers enforcing civil debt, are not peace officers. New York City Marshals are regulated by the New York City Department of Investigation.

Private communities

A number of private communities have their own public safety departments. A limited number of personnel are New York State peace officers after completing the New York State Peace Officer Standard of Training (POST) course. This grants them very limited peace officer authority within their geographical area of employment in New York City.

Prosecuting attorneys

In New York State, each county has an elected district attorney who is responsible for the prosecution of violations of New York state laws. Federal law in the city of New York is prosecuted by the U.S. Attorney for the Southern District of New York or the United States Attorney for the Eastern District of New York.
