The statewide criminal history kept by the Ohio Bureau of Criminal Investigation is closed to the public in Ohio: it is released to its subject and to authorized employers and licensing agencies, and a member of the public uses the court's own case index instead.

Arrest Records Kept Locally in Hamilton
The Butler County Sheriff's Office and the agency that reports for Hamilton (filed by the FBI as Hamilton Police Department) keep the arrest records in and around Hamilton: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
The FBI's agency list also places these agencies in Butler County: Miami University (campus police); Butler County Metroparks (other agency); each keeps the records of its own arrests.
The Sharonville Police Department is listed by the FBI across two counties including Butler County, so its arrests are not broken out for Butler County here.
Together, the ten agencies in Butler County with all twelve months of 2025 on file reported 6,118 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
The agencies and their counts, year by year, are in Hamilton arrest records.
