Darke County, Ohio, has about 51,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Darke County Sheriff's Office and five 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 Darke 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 Darke County
The Darke County Sheriff's Office is the county agency that reports arrests to the FBI for Darke County. It reported 318 arrests for 2025.
Arrests inside five 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:
- Greenville, 12,701 residents: 268 arrests reported for 2023.
- Arcanum, 2,333 residents: 10 arrests reported for 2024.
- Union City, 1,564 residents.
- Ansonia, 1,149 residents: 1,152 arrests reported for 2025.

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 Darke 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.

Through July 2026, the three agencies with every month so far on file reported 1,266 arrests, against 1,540 in the same months of 2025.

Booking: Where People Arrested in Darke County Are Held
The county jail is where a person arrested in Darke 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 2023 the jail held about 20 people, down from about 29 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 39 beds, and it ran at 74 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 Darke County
For Darke County the place to look is the case index of the Darke County Court of Common Pleas, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at darkecountycommonpleas.com, phone 226 705 8349).
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 Darke County
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 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 Darke County Sheriff's Office: ask its records unit.
- An arrest in Greenville, Arcanum, Union City, Ansonia or New Madison: the records unit of the agency that reports for that city; the city guides linked above name each city's records office.
- The court file of a case that was filed: the Darke County Court of Common Pleas, through the court records page at darkecountycommonpleas.com, phone 226 705 8349.
