The Michigan Criminal History and Your Own Copy
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. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it. The search is on the Michigan State Police site.
Arrest Records Kept Locally in Ann Arbor
The Washtenaw County Sheriff's Office and the agency that reports for Ann Arbor (filed by the FBI as Ann Arbor Police Department) keep the arrest records in and around Ann Arbor: 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 one other agency, three campus police departments and one state police unit in Washtenaw County (the arrest records guide names each one); each keeps the records of its own arrests.
Together, the eight agencies in Washtenaw County with all twelve months of 2025 on file reported 3,408 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 Ann Arbor arrest records.
