Finding Someone in Custody in Sidney
The county jail, run by the Shelby County Sheriff's Office, holds everyone kept in custody after an arrest in Sidney, from every agency.
SearchSystems opened and checked the custody page of the Shelby County Sheriff's Office at shelby.miamivalleyjails.org (page title: Shelby County, Ohio | Persons Currently In Custody), which answered when SearchSystems opened it on October 9, 2026.
That page is the place to look for someone 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.
The Shelby County Jail by the Numbers
On an average day in 2023 the jail held about 94 people, down from about 170 in 2019. Its rated capacity in 2023 was 188 beds, and it ran at 50 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
Shelby County has about 48,000 residents (2024 Census Bureau estimate), so the jail holds about 20 people for every 10,000 residents.
Who Books People Into the Shelby County Jail
The Shelby County Sheriff's Office and the agency that reports for Sidney (filed by the FBI as Sidney Police Department) make the arrests that end in a booking in and around Sidney.
The largest arrest counts reported to the FBI were Port Jefferson's 1,152 for 2025, Sidney's 607 for 2025 and the Shelby County Sheriff's Office's 261 for 2025.
Together, the four agencies in Shelby County with all twelve months of 2025 on file reported 2,031 arrests to the FBI that year. Those kept in custody were booked into the county jail; a person cited and released at the scene was not.
The counts, agency by agency and year by year, are in Sidney arrest records.
From the Jail to State Prison
A sentence of more than a year is served in state prison, not the jail; the Ohio Department of Rehabilitation and Correction lists its inmates at appgateway.drc.ohio.gov/OffenderSearch.
