Warren County, Ohio, has about 256,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Warren County Sheriff's Office and ten 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 Prosecuting Attorney files charges, a case in the Warren County Court of Common Pleas. 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 Warren County
The Warren County Sheriff's Office is the county agency that reports arrests to the FBI for Warren County. It reported 449 arrests for 2025.
Arrests inside eight 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:
- Mason, 36,046 residents: 299 arrests reported for 2025.
- Lebanon, 21,995 residents: 260 arrests reported for 2025.
- Springboro, 19,646 residents: 181 arrests reported for 2025.
- Franklin, 11,758 residents: 1,279 arrests reported for 2024.
- Carlisle, 5,855 residents: 23 arrests reported for 2025.
- Waynesville, 2,862 residents: 5 arrests reported for 2024.
- Morrow, 2,199 residents.
- Harveysburg, 579 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.
The Monroe Police Department, the Middletown Police Department and the Loveland Police Department are each listed by the FBI across several counties including Warren County, so their arrests are not broken out for Warren County here.

Booking: Where People Arrested in Warren County Are Held
A person kept in custody after an arrest in Warren County 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 270 people, down from about 300 in 2019. Its rated capacity in 2023 was 498 beds, and it ran at 55 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 Warren County
Whether someone was arrested in Warren County, and what came of it, shows up in two places: the case index of the Warren County Court of Common Pleas, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at probate.co.warren.oh.us/search.php); the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at prosecutor.warrencountyohio.gov/GenInfo/Staff/Index, phone 513-695-1325).
Ohio does not let the public search another person's statewide criminal history. The record kept by the Ohio Bureau of Criminal Investigation goes to the person it belongs to and to employers and agencies the law authorizes; for everyone else the court's own case index is the public record of an arrest that led to a charge.
Getting a Copy of an Arrest Record in Warren 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 Ohio Public Records Act the agency must answer promptly, within a reasonable period of time, and it may charge the actual cost of copying.
- An arrest by the Warren County Sheriff's Office: ask its records unit, reached through the office at 866-345-1884.
- An arrest in Mason, Lebanon, Springboro, Franklin, Carlisle, Waynesville or another of the cities listed above: the records unit of the agency that reports for that city; the city guides linked above name each city's records office.
- A defendant who has been charged gets the report through the case: the Prosecuting Attorney, 513-695-1325, handles discovery for pending cases.
