Piatt County, Illinois, has about 17,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Piatt County Sheriff's Office and four city agencies. An arrest 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 Piatt County. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

Who Makes Arrests in Piatt County
The Piatt County Sheriff's Office is the county agency that reports arrests to the FBI for Piatt County. It reported 116 arrests for 2025.
Arrests inside four of the county's cities are reported to the FBI by an agency of the city's own, listed here with the Census population and what each reported:
- Monticello, 6,010 residents: 26 arrests reported for 2025.
- Bement, 1,452 residents: 3 arrests reported for 2025.
- Atwood, 1,097 residents: 21 arrests reported for 2025.
- Mansfield, 918 residents.
A city on that list is reported separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
How Many Arrests Each Agency Reports in Piatt County
Each agency reports its arrests to the FBI by month, and the FBI publishes them 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.
- Piatt County Sheriff's Office: 116 for 2025, 129 for 2024 and 155 for 2022; 2023 is missing months.

Through July 2026, the three agencies with every month so far on file reported 84 arrests, against 85 in the same months of 2025.
Booking: Where People Arrested in Piatt County Are Held
The county jail is where a person arrested in Piatt County 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 2019 the jail held about 21 people. Its rated capacity in 2019 was 76 beds, and it ran at 28 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
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 Piatt County
Whether someone was arrested in Piatt County, and what came of it, shows up in two places: the case index of the Circuit Court of Piatt County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at circuitclerk.piatt.gov); the State's Attorney, which decides whether an arrest becomes a charge (its page is at piatt.gov/departments/states_attorneys_office.php, phone 217-762-2574).
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 Piatt County
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. 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.
- An arrest by the Piatt County Sheriff's Office: ask its records unit.
- An arrest in Monticello, Bement, Atwood or Mansfield: the records unit of the agency that reports for that city.
- A defendant who has been charged gets the report through the case: the State's Attorney, 217-762-2574, handles discovery for pending cases.
- The court file of a case that was filed: the Circuit Court of Piatt County, through the court records page at circuitclerk.piatt.gov.
- Your own statewide record: a name-based or fingerprint-based request to the Illinois State Police.
