Beach Park, Illinois, in Lake County, has about 14,000 residents (2024 Census Bureau estimate). 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 State's Attorney files charges, a case in the Circuit Court of Lake County. This guide says who keeps each one, what it costs and who may see it.
This guide covers who makes arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Beach Park
The FBI lists no arrest reporting agency under the name of Beach Park. In Lake County the county agency that reports arrests is the Lake County Sheriff's Office.
The FBI's agency list also places these agencies in Lake County: the College of Lake County (campus police); Lake County Forest Preserve, the Round Lake Park District and the Zion Park District (other).
Booking: Where People Arrested in Beach Park Are Held
The county jail is where a person arrested in Beach Park 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 2024 the jail held about 510 people, down from about 630 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 740 beds, and it ran at 85 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 Lake County Sheriff's Office at lakecountyil.gov/2031/Inmate-Information (page title: Inmate Information | Lake County, IL), 29 S Martin Luther King Jr Avenue, Waukegan, IL 60085, a site that blocks automated checks (HTTP 429), so open it in a browser.
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 Illinois Department of Corrections lists its inmates at idoc.illinois.gov/offender/inmatesearch.html.
How to Find Out About an Arrest in Beach Park
An arrest in Beach Park can be traced in two places, depending on where the case stands: the custody page of the Lake County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Circuit Court of Lake County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at ilsos.gov/departments/archives/databases/lake.html, phone 815-753-1807).
Illinois is one of the states that lets anyone look up another person's statewide criminal history: conviction information is public under the Uniform Conviction Information Act, through the Illinois 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 Beach Park
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. Under the Illinois Freedom of Information Act the agency must answer within 5 business days, with one 5-day extension, and it may charge copying only after the first 50 pages.
