Troy, Illinois, in Madison County, has about 12,000 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 Madison 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 Troy
The FBI lists Troy with an arrest reporting agency of its own, filed as Troy Police Department. It reported 162 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 Madison County Sheriff's Office is the county agency. It reported 1,121 arrests for 2025.
The FBI's agency list also places these agencies in Madison County: Norfolk Southern Railway in Madison County and Terminal Railroad Association (other); Southern Illinois University at Edwardsville (campus police).
How Many Arrests Troy 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.
- Troy: 162 for 2025, 163 for 2024, 176 for 2023, 231 for 2022 and 219 for 2021.
Troy's 162 arrests in 2025 were down 0.6 percent from 163 in 2024.
Across Madison County, the 20 agencies with all twelve months of 2025 on file reported 8,317 arrests between them.
Booking: Where People Arrested in Troy Are Held
The county jail is where a person arrested in Troy and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2023 the jail held about 240 people, down from about 310 in 2019. Its rated capacity in 2023 was 306 beds, and it ran at 80 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Troy
For Troy the place to look is the case index of the Circuit Court of Madison County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at madisoncountyil.gov/departments/circuit_clerk/court_records_search.php, phone (800) 250-9884).
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 Troy
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.
