Investigation (DOI)


The New York City Department of Investigation (DOI) is the City's Inspector General, with independent oversight of City government, including each mayoral agency, City vendors, and an array of boards and commissions. Our investigations may involve any agency, officer, elected official or employee of the City, as well as those who do business with or receive benefits from the City. We are one of the oldest law enforcement agencies in the country and an international leader in the effort to combat corruption in public institutions.

The agency is imbued with unique powers that support its independence and fact-finding mission, including the power to issue subpoenas and take testimony under oath. For more than 140 years, DOI has been the City's anti-corruption watchdog, protecting against corruption, fraud, waste, malfeasance and misconduct and bringing an in-depth understanding of City processes and operations to the investigations it conducts.

DOI's strategy attacks corruption comprehensively through systemic investigations that lead to high-impact arrests, preventive internal controls and operational reforms that improve the way the City runs. Visitors to this website can view our public reports and releases, read about our history, and better understand DOI's distinct role in City government.
