Monroe County, Michigan, has about 156,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Monroe County Sheriff's Office, six city agencies and one state 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 Monroe County Circuit Court. 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 Monroe County
The Monroe County Sheriff's Office is the county agency that reports arrests to the FBI for Monroe County. It reported 1,204 arrests for 2025.
The FBI lists five cities in Monroe County with a reporting agency of their own, with the Census population and what each reported:
- Monroe, 20,177 residents: 484 arrests reported for 2025.
- Dundee, 6,006 residents: 1,159 arrests reported for 2025.
- Carleton, 2,302 residents.
- South Rockwood, 1,583 residents.
- Luna Pier, 1,357 residents: 1,159 arrests reported for 2025.
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 Milan Police Department is listed by the FBI across two counties including Monroe County, so its arrests are not broken out for Monroe County here.

Booking: Where People Arrested in Monroe County Are Held
A person kept in custody after an arrest in Monroe 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 250 people, down from about 340 in 2019. Its rated capacity in 2023 was 363 beds, and it ran at 68 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 Monroe County Sheriff's Office at co.monroe.mi.us/891/Inmate-Lookup (page title: Inmate Lookup | Monroe County, MI), phone 800-770-7657, which answered when SearchSystems opened it on September 23, 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.

How to Find Out About an Arrest in Monroe County
An arrest in Monroe County can be traced in three places, depending on where the case stands: the custody page of the Monroe County Sheriff's Office described above, for anyone booked into the county jail; MiCOURT Case Search, the Michigan courts' statewide case search; not every court has joined, which shows whether charges were filed; the Prosecuting Attorney, which decides whether an arrest becomes a charge (its page is at co.monroe.mi.us/521/Prosecuting-Attorney, phone 734-240-7600).
Michigan is one of the states that lets anyone look up another person's statewide criminal history: ICHAT lets anyone search public criminal history by name, for $10 a search, through the Michigan State Police. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Monroe County
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Michigan Freedom of Information Act the agency must answer within 5 business days, with a 10-day extension, and it may charge labor and copying, at rates the law caps.
- An arrest by the Monroe County Sheriff's Office: ask its records unit, reached through the office at 800-770-7657.
- An arrest in Monroe, Dundee, Carleton, South Rockwood or Luna Pier: the records unit of the agency that reports for that city.
- An arrest by the Monroe County State Police: the records office of the agency involved.
- A defendant who has been charged gets the report through the case: the Prosecuting Attorney, 734-240-7600, handles discovery for pending cases.
- Your own statewide record: the same request described above, for your own name.
Cities in Monroe County: Who Reports the Arrests
The FBI lists a separate arrest reporting agency for five of the eight cities in Monroe County: Monroe, Dundee, Carleton, South Rockwood and Luna Pier.

The FBI's list also carries the Erie Township Police Department as a city agency in Monroe County; Erie Township is not among the cities above.
Wherever in the county the arrest happens, a person kept in custody goes to the county jail and the case goes to the Monroe County Circuit Court.
