St. Charles, Illinois, in Kane County, has about 33,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the State's Attorney files charges, a case in the Circuit Court of Kane County. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in St. Charles
The FBI lists St. Charles with an arrest reporting agency of its own, filed as St. Charles Police Department. It reported 516 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Kane County Sheriff's Office is the county agency. It reported 940 arrests for 2025.
The FBI's agency list also places these agencies in Kane County: Aurora University, Waubonsee Community College and Elgin Community College (campus police); Kane County Forest Preserve and the Fox Valley Park District (other).
How Many Arrests St. Charles Reports
The FBI publishes every agency's monthly arrest counts on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- St. Charles: 516 for 2025, 630 for 2024, 472 for 2023 and 590 for 2022.
St. Charles's 516 arrests in 2025 were down 18 percent from 630 in 2024.
Through July 2026, St. Charles reported 338 arrests, against 299 in the same months of 2025.
Across Kane County, the 19 agencies with all twelve months of 2025 on file reported 9,151 arrests between them.
Booking: Where People Arrested in St. Charles Are Held
A person kept in custody after an arrest in St. Charles is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2023 the jail held about 340 people, down from about 510 in 2019. Its rated capacity in 2023 was 640 beds, and it ran at 53 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Kane County Sheriff's Office at kanesheriff.com/Pages/Detainee-Search.aspx (page title: Detainee Search), phone 630-232-6840, which answered when SearchSystems opened it on October 4, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A person sentenced to prison serves the sentence in a facility of the Illinois Department of Corrections, whose inmate locator is at idoc.illinois.gov/offender/inmatesearch.html.
How to Find Out About an Arrest in St. Charles
An arrest in St. Charles can be traced in three places, depending on where the case stands: the custody page of the Kane County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Circuit Court of Kane County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at cic.countyofkane.org/pages/online-court-records.aspx); the State's Attorney, which decides whether an arrest becomes a charge (its page is at sao.kanecountyil.gov, phone (630) 232-3500).
Illinois is one of the states that lets anyone look up another person's statewide criminal history: conviction information is public under the Uniform Conviction Information Act, through the Illinois State Police. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in St. Charles
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Illinois Freedom of Information Act the agency must answer within 5 business days, with one 5-day extension, and it may charge copying only after the first 50 pages.
