Reviewed and updated October 9, 2026 by the SearchSystems.net editorial team. The arrest and crime counts are the ones each agency reported to the FBI, as the FBI held them on October 8, 2026.

DuPage County, Illinois, has about 937,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from DuPage County depends on where the incident happened: the DuPage County Sheriff's Office for the unincorporated county, the agency that reports for the city inside a city. This guide names each agency, where its records page is and what the Illinois Freedom of Information Act requires of it.
This guide covers which agency, the sheriff's reports, the cities' reports, how many reports, what the law requires and common questions.

Which Agency Holds a Report from DuPage County
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
In DuPage County that is the DuPage County Sheriff's Office for the unincorporated county and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
The FBI's agency list also places two other agencies and two campus police departments in DuPage County, each with a records office of its own.
The Hanover Park Police Department, the St. Charles Police Department, the Bolingbrook Police Department and two more are each listed by the FBI across several counties including DuPage County, so their arrests are not broken out for DuPage County here.
