Reviewed and updated October 9, 2026 by the SearchSystems.net editorial team. The arrest counts are the ones each agency reported to the FBI, as the FBI held them on October 8, 2026.

Miami County, Ohio, has about 112,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Miami County Sheriff's Office, five city agencies and one other agency. 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 Miami 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 Miami County
The Miami County Sheriff's Office is the county agency that reports arrests to the FBI for Miami County. It reported 459 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:
- Troy, 27,122 residents: 744 arrests reported for 2025.
- Piqua, 20,940 residents: 814 arrests reported for 2025.
- Tipp City, 10,596 residents: 88 arrests reported for 2025.
- West Milton, 4,855 residents: 69 arrests reported for 2024.
- Covington, 2,622 residents: 41 arrests reported for 2022.
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 Union Police Department and the Huber Heights Police Department are each listed by the FBI across several counties including Miami County, so their arrests are not broken out for Miami County here.
The FBI's agency list also places one more agency in Miami County: the Miami County Park District (other).
How Many Arrests Each Agency Reports in Miami 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.
- Piqua: 814 for 2025, 904 for 2024, 956 for 2023, 997 for 2022, 1,046 for 2021 and 1,014 for 2020.
- Troy: 744 for 2025, 785 for 2024, 774 for 2023, 1,106 for 2022, 1,036 for 2021 and 1,042 for 2020.
- Miami County Sheriff's Office: 459 for 2025, 482 for 2024, 611 for 2023, 638 for 2022, 680 for 2021 and 582 for 2020.
- Tipp City: 88 for 2025, 188 for 2023, 158 for 2022 and 175 for 2021; 2024 is missing months.
- West Milton: 69 for 2024.
- Covington: 41 for 2022, 65 for 2021, 41 for 2020 and 57 for 2019.
Together, the four agencies with all twelve months of 2025 on file reported 2,105 arrests that year. The three of them with both 2025 and 2024 complete reported 2,017 in 2025 against 2,171 in 2024, down 7.1 percent.
Through June 2026, the four agencies with every month so far on file reported 1,041 arrests, against 1,067 in the same months of 2025.
West Milton reported only part of 2025 (3 months) and is left out of the totals.
Booking: Where People Arrested in Miami County Are Held
A person kept in custody after an arrest in Miami 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 150 people, down from about 200 in 2019. Its rated capacity in 2023 was 295 beds, and it ran at 52 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
A sentence of more than a year is served in state prison; the Ohio Department of Rehabilitation and Correction lists its inmates at appgateway.drc.ohio.gov/OffenderSearch.
How to Find Out About an Arrest in Miami County
For Miami County the place to look is the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at miamicountyohio.gov/prosecuting-attorney, phone (937) 440-3928).
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 Miami 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 Miami County Sheriff's Office: ask its records unit.
- An arrest in Troy, Piqua, Tipp City, West Milton or Covington: the records unit of the agency that reports for that city; the city guides linked above name each city's records office.
- An arrest by the Miami County Park District: the records office of the agency involved.
- A defendant who has been charged gets the report through the case: the Prosecuting Attorney, (937) 440-3928, handles discovery for pending cases.
- Your own statewide record: a fingerprint-based WebCheck at any WebCheck location.
Cities in Miami County: Who Reports the Arrests
