About this guide

Kane County, Illinois, has about 521,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Kane County depends on where the incident happened: the Kane 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 Kane County

The report of an incident is released by the agency that took it; the court and the jail hold their own records of the same event, but not the report.

In Kane County that is the Kane 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 three campus police departments and two other agencies in Kane County, each with a records office of its own.

The Wayne Police Department, the Montgomery Police Department, the Huntley Police Department and three more are each listed by the FBI across several counties including Kane County, so their arrests are not broken out for Kane County here.
