Welcome to the website of the New York City Department of Investigation (DOI), the City's independent anti-corruption agency and one of the oldest law enforcement agencies in the country. Our work helps to ensure New Yorkers have the honest government they deserve.
DOI’s investigations expose and stop corruption, waste, and fraud, and we seek to prevent future misconduct by proposing policy and procedural changes to address the vulnerabilities we uncover. Our public reports provide transparency about our investigative findings and convey our recommendations for necessary changes in City government operations. DOI often partners with state and federal prosecutors as well as other law enforcement agencies on the investigations we conduct; and investigations can result in arrest or disciplinary action, or both.
DOI also investigates potential conflicts of interest that may result in referrals to the Conflicts of Interest Board, the City’s ethics agency, as well as claims of retaliation against employees of agencies and City contractors who report misconduct and are protected by the
City’s Whistleblower Law. In addition, DOI provides other critical services to the City, including background investigations for certain City employees and vendor name checks for City-funded vendors.
DOI’s work instills confidence in City government, and in the vast majority of City employees who serve New Yorkers every day with dedication and integrity.
Our mission cannot succeed without the public's participation. City employees and members of the public are often our most valuable source of information – our eyes and ears throughout the City. If you witness corruption, waste, fraud or abuse you can report it to DOI
online here and through our hotline at 212-3-NYC-DOI.
Combating corruption, fraud, and waste strengthens government and New York City.
