The DOI will make public a 40-page report and hold a press conference about the "allegations involving the Mayor's security detail" on Thursday morning.
Law enforcement sources said the probe concerned use of city resources for personal use, a possible violation of New York's Conflicts of Interest Law.
Hizzoner came under scrutiny in 2019 for using taxpayer funds to cover the costs of his security detail while traveling for his long-shot presidential bid.
At the time, de Blasio referred inquiries about the use of public funds for the out-of-town campaign trips to the NYPD, saying it was up to the department to "address all the question around security."
He also got flak after the Executive Protection Unit reportedly helped move daughter Chiara de Blasio into Gracie Mansion in 2018.
Members of the unit were questioned by DOI investigators about the move last year, sources said.
Investigators have also interviewed several personal aides to the mayor and first lady Chirlane McCray — known as body people — in recent months, a City Hall insider said.
The mayor has also admitted that son Dante de Blasio caught rides from the NYPD while studying at Yale University due to "threats" against the city's entire first family early in his administration.
City Hall declined to comment ahead of the DOI report's public release.
No, no, they didn’t HELP. The officers actually physically carried the furniture from her apartment to be transported on a police van like movers! Details matter.
