Message from the Commissioner

As New York City’s Inspector General, the Department of Investigation (DOI) is an independent and unique oversight agency, and one of the nation’s oldest law enforcement entities. DOI’s core mission is to detect, stop, and prevent corruption, fraud, waste and mismanagement involving City government. Our work has a profound impact on governing in New York City. DOI investigations protect public funds and the integrity of public services, provide accountability that encourages public confidence in government and its officials, and prevent corruption and fraud from taking root through recommendations that strengthen internal controls and advance best practices.

In this way, DOI helps ensure that the City operates with integrity, transparency, and fairness for all New Yorkers.

I am so pleased to welcome you to our public website, which features a wealth of information about DOI, including significant events during the agency’s 152-year-plus history, announcements on its current investigations and public reports, and a database that features DOI’s policy and procedure recommendations since 2014. The website also describes the statutes that empower DOI and the units that make up the agency.

DOI operates with independence and a steadfast commitment to follow the facts without fear or favor. Corruption, fraud and waste undercut the effectiveness of City services as well as access to important programs that provide critical needs. Our work also supports the vast majority of City employees who serve New Yorkers every day with dedication and integrity.

Our mission to combat wrongdoing cannot fully 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 through our hotline at 212-3-NYC-DOI and online here.

Know that DOI is working hard to ensure City government operates with integrity, efficiency, accountability and fairness – for all New Yorkers.

Regards,
Nadia I. Shihata
DOI Commissioner
