Welcome to DOI’s website. Here you will find information about this agency’s history, significant cases and current arrests.

DOI’s major functions include investigating and referring for prosecution cases of fraud, corruption and unethical conduct by City employees, contractors and others who receive City money. We are also charged with studying agency procedures to identify corruption hazards and recommending improvements in order to reduce the City’s vulnerability to fraud, waste and corruption. We investigate backgrounds of individuals selected to work in decision-making or sensitive City jobs, and VENDEX those who do business with the City, to determine if they are suited to serve the public trust.

The enormous range of this docket means that DOI handles at any one time hundreds of complaints. Every week, in fact, almost every day, the agency’s work is punctuated by incoming matters including urgent situations that require the immediate attention of a cadre of top-flight investigators and members of the executive staff.

DOI goes where the cases and evidence take us without regard to politics or agendas. There are real victims behind the investigations DOI conducts. If, for example, inspectors decide to take bribes in lieu of inspecting the gas lines beneath our streets, that raises a public safety issue, or if school custodians steal from the money they are given to maintain our schools, the result is those schools will be dirtier, shoddier places, and the City’s school children and teachers will be negatively affected.

In a time of diminishing resources, we continue to find new and effective ways to address the problems challenging the City. We try to identify and fix potential corruption hazards before they develop into criminal prosecutions. We educate City employees and contractors through our anti-corruption presentations. And, when DOI investigations find that money has been stolen from the City, we make every effort to ensure that those funds are recovered.

As you learn more about the agency by perusing this website, you'll see that we not only make arrests in high-impact cases but we also offer recommendations on how to improve government operations. I think you’ll be impressed by our ability to maximize our resources as we continue to provide to the City and its citizens the promotion of honesty and integrity within City government.
