Blue Ash, Ohio, in Hamilton County, has about 14,000 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 Hamilton 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 Blue Ash
The FBI lists Blue Ash with an arrest reporting agency of its own, filed as Blue Ash Police Department. It reported 241 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 Hamilton County Sheriff's Office is the county agency. It reported 1,338 arrests for 2025.
The FBI's agency list also places these agencies in Hamilton County: the University of Cincinnati, Mount St. Joseph University and Cincinnati State College (campus police); the Hamilton County Park District (other).
How Many Arrests Blue Ash 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.
- Blue Ash: 241 for 2025, 212 for 2024, 296 for 2023, 304 for 2022, 239 for 2021 and 366 for 2020.
Blue Ash's 241 arrests in 2025 were up 14 percent from 212 in 2024.
Through August 2026, Blue Ash reported 163 arrests, against 161 in the same months of 2025.
Across Hamilton County, the 32 agencies with all twelve months of 2025 on file reported 14,329 arrests between them.
Booking: Where People Arrested in Blue Ash Are Held
A person kept in custody after an arrest in Blue Ash 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 2024 the jail held about 1,140 people, down from about 1,800 in 2019. Its rated capacity in 2023, the last year with a capacity figure, was 2,005 beds, and it ran at 57 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Hamilton County Sheriff's Office at hcso.org/justice-center-services/inmate-search (page title: Hamilton County Justice Center | Inmate Search | Hamilton County Sheriff's Office), which answered when SearchSystems opened it on October 1, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
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 Blue Ash
Whether someone was arrested in Blue Ash, and what came of it, shows up in three places: the custody page of the Hamilton County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Hamilton County Court of Common Pleas, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at hamiltoncountyohio.gov/community/court_records.php); the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at hamiltoncountyohio.gov/government/courts/prosecutors_office/index.php).
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 Blue Ash
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.
