Delafield, Wisconsin, in Waukesha County, has about 7,300 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 Delafield
The FBI lists Delafield with an arrest reporting agency of its own, filed as Delafield Police Department. It reported 174 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 Delafield 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.
- Delafield: 174 for 2025, 243 for 2024, 183 for 2023, 188 for 2022, 159 for 2021 and 233 for 2020.
Delafield's 174 arrests in 2025 were down 28 percent from 243 in 2024.
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 Delafield Are Held
The county jail is where a person arrested in Delafield 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 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.
How to Find Out About an Arrest in Delafield
Whether someone was arrested in Delafield, and what came of it, shows up in three places: the custody page of the Waukesha County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Waukesha County Circuit Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at waukeshacounty.gov/circuit-courts/information-pages/court-record-in...); the District Attorney, which decides whether an arrest becomes a charge (its page is at waukeshacounty.gov/district-attorney, phone 262-548-7076).

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 Delafield
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. 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.
