Oswego Arrest Records: Who Makes Arrests, Where People Are Booked and How to Get the Report

Who Makes Arrests in Oswego

The FBI lists Oswego with an arrest reporting agency of its own, filed as Oswego Police Department. It reported 329 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 Kendall County Sheriff's Office is the county agency. It reported 335 arrests for 2025.

How Many Arrests Oswego 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.

• Oswego: 329 for 2025, 314 for 2024, 295 for 2023, 272 for 2022 and 188 for 2021.

Oswego's 329 arrests in 2025 were up 4.8 percent from 314 in 2024.

Through August 2026, Oswego reported 188 arrests, against 225 in the same months of 2025.

Across Kendall County, the five agencies with all twelve months of 2025 on file reported 1,135 arrests between them.

Booking: Where People Arrested in Oswego Are Held

The county jail is where a person arrested in Oswego 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 2021 the jail held about 140 people, down from about 140 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 203 beds, and it ran at 71 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 Oswego

An arrest in Oswego can be traced in two places, depending on where the case stands: the case index of the Circuit Court of Kendall County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at kendallcountyil.gov/offices/circuit-clerk/online-court-records, phone 630-553-4183); the State's Attorney, which decides whether an arrest becomes a charge (its page is at kendallcountyil.gov/offices/state-s-attorney, phone 630-553-4157).

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 Oswego

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.
