Coal City, Illinois, in Grundy County, has about 5,800 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 Grundy 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 Coal City
The FBI lists Coal City with an arrest reporting agency of its own, filed as Coal City Police Department. It reported 94 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 Grundy County Sheriff's Office is the county agency. It reported 330 arrests for 2025.
How Many Arrests Coal City 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.
- Coal City: 94 for 2025, 174 for 2024, 87 for 2023 and 62 for 2021; 2022 is missing months.
Coal City's 94 arrests in 2025 were down 46 percent from 174 in 2024.
Across Grundy County, the six agencies with all twelve months of 2025 on file reported 1,030 arrests between them.
Booking: Where People Arrested in Coal City Are Held
A person kept in custody after an arrest in Coal City 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 2019 the jail held about 33 people. Its rated capacity in 2019 was 67 beds, and it ran at 49 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 Coal City
Whether someone was arrested in Coal City, and what came of it, shows up in two places: the case index of the Circuit Court of Grundy County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at grundycountyil.gov/services/circuit_court_clerk, phone (815) 941-3256); the State's Attorney, which decides whether an arrest becomes a charge (its page is at grundycountyil.gov/services/states_attorney/index.php, phone (815) 941-3276).
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 Coal City
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.
