Newton, Iowa, in Jasper County, has about 16,000 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 County Attorney files charges, a case in the Iowa District Court for Jasper County. 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 Newton
The FBI lists Newton with an arrest reporting agency of its own, filed as Newton Police Department. It reported 579 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 Jasper County Sheriff's Office is the county agency. It reported 300 arrests for 2025.
How Many Arrests Newton Reports
The FBI publishes every agency's monthly arrest counts 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.
- Newton: 579 for 2025, 616 for 2024, 700 for 2023, 647 for 2022, 570 for 2021 and 746 for 2020.
Newton's 579 arrests in 2025 were down 6 percent from 616 in 2024.
Through August 2026, Newton reported 279 arrests, against 414 in the same months of 2025.
Across Jasper County, the five agencies with all twelve months of 2025 on file reported 928 arrests between them.
Booking: Where People Arrested in Newton Are Held
A person kept in custody after an arrest in Newton 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 2019 the jail held about 67 people. Its rated capacity in 2019 was 127 beds, and it ran at 53 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 Jasper County Sheriff's Office at jasperso.com/inmate-roster (page title: Inmate Roster | Jasper SO), which answered when SearchSystems opened it on September 24, 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 Iowa Department of Corrections lists its inmates at doc.iowa.gov/inmate-family-services.
How to Find Out About an Arrest in Newton
Whether someone was arrested in Newton, and what came of it, shows up in three places: the custody page of the Jasper County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Iowa District Court for Jasper County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at iowacourts.gov/iowa-courts/district-court/judicial-district-5/distr..., phone 641-792-3255); the County Attorney, which decides whether an arrest becomes a charge (its page is at jasperia.org/attorney, phone 641-792-5010).

Iowa is one of the states that lets anyone look up another person's statewide criminal history: anyone can request a name-based criminal history check online, through the Iowa Division of Criminal Investigation. 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 Newton
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. Under the Iowa Open Records Law (Chapter 22) the agency must answer without delay; the law sets no fixed number of days, and a delay past 20 days must be justified, and it may charge the actual cost of copying and retrieval.
