Platteville, Wisconsin, in Grant County, has about 12,000 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 District Attorney files charges, a case in the Grant County Circuit Court. 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 Platteville
The FBI lists Platteville with an arrest reporting agency of its own, filed as Platteville Police Department. It reported 362 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 Grant County Sheriff's Office is the county agency. It reported 507 arrests for 2024.
The FBI's agency list also places one more agency in Grant County: the University of Wisconsin at Platteville (campus police).
How Many Arrests Platteville 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.
- Platteville: 362 for 2025, 472 for 2024, 658 for 2023, 617 for 2022, 575 for 2021 and 619 for 2020.

Booking: Where People Arrested in Platteville Are Held
The county jail is where a person arrested in Platteville and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.
On an average day in 2025 the jail held about 46 people, down from about 48 in 2019. Its rated capacity in 2025 was 101 beds, and it ran at 45 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Platteville
Whether someone was arrested in Platteville, and what came of it, shows up in two places: the case index of the Grant County Circuit Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at wicourts.gov/casesearch.htm); the District Attorney, which decides whether an arrest becomes a charge (its page is at gcinternetwebsite.co.grant.wi.gov/district-attorney, phone (608) 723-4237).
Statewide, Wisconsin Circuit Court Access is the free statewide case search of every circuit court.
Wisconsin is one of the states that lets anyone look up another person's statewide criminal history: the Wisconsin Online Record Check System lets anyone run a name-based check, through the Wisconsin Department of Justice. 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 Platteville
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 Wisconsin Public Records Law the agency must answer as soon as practicable and without delay; the law sets no number of days, and it may charge the actual cost of copying and locating, with no charge for the first $50 of locating.
