Brookfield, Wisconsin, in Waukesha County, has about 41,000 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 Waukesha 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 Brookfield
The FBI lists Brookfield with an arrest reporting agency of its own, filed as Brookfield Township Police Department. It reported 227 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 Waukesha County Sheriff's Office is the county agency. It reported 2,041 arrests for 2025.
How Many Arrests Brookfield (township) 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.

Across Waukesha County, the 16 agencies with all twelve months of 2025 on file reported 8,658 arrests between them.
Booking: Where People Arrested in Brookfield Are Held
A person kept in custody after an arrest in Brookfield 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 2025 the jail held about 470 people, down from about 500 in 2019. Its rated capacity in 2025 was 807 beds, and it ran at 59 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 Waukesha County Sheriff's Office at waukeshacounty.gov/sheriff/jail-division/current-inmate-list (page title: Current Inmate List | Waukesha County), 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.
A sentence of more than a year is served in state prison; the Wisconsin Department of Corrections lists its inmates at appsdoc.wi.gov/lop/welcome.

That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
