South Sioux City, Nebraska, in Dakota County, has about 14,000 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 Dakota County District 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.

Booking: Where People Arrested in South Sioux City Are Held
A person kept in custody after an arrest in South Sioux City 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 110 people. Its rated capacity in 2019 was 136 beds, and it ran at 83 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 South Sioux City
Whether someone was arrested in South Sioux City, and what came of it, shows up in two places: the case index of the Dakota County District Court, kept by the Clerk of the District Court, which shows whether charges were filed and the next court date; the County Attorney, which decides whether an arrest becomes a charge (its page is at dakotacounty.ne.gov/attorney-county, phone 402-987-2151).
The court records page SearchSystems verified for the county, at nebraskajudicial.gov/courts/dakota-county-court (page title: Dakota County Court | Nebraska Judicial Branch), phone 402-987-2145, belongs to a lower court, not to the Dakota County District Court.
Statewide, Nebraska Trial Court Case Search is the Nebraska Judicial Branch's statewide case search, with a fee per search.
Nebraska is one of the states that lets anyone look up another person's statewide criminal history: the Patrol sells name-based criminal history checks to anyone online, through the Nebraska State Patrol. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
