Marysville, Ohio, in Union County, has about 29,000 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 Prosecuting Attorney files charges, a case in the Union County Court of Common Pleas. 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 Marysville
The FBI lists Marysville with an arrest reporting agency of its own, filed as Marysville Police Department. It reported 185 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 Union County Sheriff's Office is the county agency. It reported 86 arrests for 2025.
How Many Arrests Marysville Reports
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.
- Marysville: 185 for 2025, 211 for 2024, 237 for 2023, 228 for 2022, 251 for 2021 and 260 for 2020.
Marysville's 185 arrests in 2025 were down 12 percent from 211 in 2024.
Across Union County, the two agencies with all twelve months of 2025 on file reported 271 arrests between them.
Booking: Where People Arrested in Marysville Are Held
A person kept in custody after an arrest in Marysville 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 66 people, down from about 81 in 2019. Its rated capacity in 2023 was 74 beds, and it ran at 89 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 Marysville
For Marysville the place to look is the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at unioncountyohio.gov/Prosecuting-Attorney, phone 937-645-4190).
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 Marysville
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.
