Cambridge, Minnesota, in Isanti County, has about 11,000 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 Isanti 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.

Who Makes Arrests in Cambridge
The FBI lists Cambridge with an arrest reporting agency of its own, filed as Cambridge Police Department. It reported 123 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 Isanti County Sheriff's Office is the county agency. It reported 99 arrests for 2025.
How Many Arrests Cambridge 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.
- Cambridge: 123 for 2025, 130 for 2024, 115 for 2023, 99 for 2022, 56 for 2021 and 318 for 2020.
Cambridge's 123 arrests in 2025 were down 5.4 percent from 130 in 2024.
Through September 2026, Cambridge reported 48 arrests, against 83 in the same months of 2025.
Across Isanti County, the four agencies with all twelve months of 2025 on file reported 260 arrests between them.
Booking: Where People Arrested in Cambridge Are Held
The county jail is where a person arrested in Cambridge 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 2021 the jail held about 23 people, down from about 50 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 111 beds, and it ran at 45 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 Isanti County Sheriff's Office at isanticountymn.gov/425/In-Custody (page title: In Custody | Isanti County, MN), 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.
How to Find Out About an Arrest in Cambridge
Whether someone was arrested in Cambridge, and what came of it, shows up in three places: the custody page of the Isanti County Sheriff's Office described above, for anyone booked into the county jail; Minnesota Court Records Online, the Minnesota Judicial Branch's free statewide case search, which shows whether charges were filed; the County Attorney, which decides whether an arrest becomes a charge (its page is at isanticountymn.gov/231/Attorney, phone 320-396-3383).
Minnesota is one of the states that lets anyone look up another person's statewide criminal history: the public criminal history search online is free and shows 15 years of convictions, through the Minnesota Bureau of Criminal Apprehension. 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 Cambridge
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Minnesota Government Data Practices Act the agency must answer promptly, within a reasonable time, and it may charge copying, and staff time for requests over 100 pages.
- An arrest by the Cambridge police: the police department's page SearchSystems verified at ci.cambridge.mn.us/your-government/departments/police (page title: Police | Cambridge, MN), phone (763) 689-9567, Monday - Thursday. 7:30 - 5:00 pm, which answered when SearchSystems opened it on September 25, 2026.
- An arrest by the Isanti County Sheriff's Office: ask its records unit.
- A defendant who has been charged gets the report through the case: the County Attorney, 320-396-3383, handles discovery for pending cases.
- Any county record that is not posted: the county records request page SearchSystems verified is at isanticountymn.gov (page title: Data Practices Requests | Isanti County, MN).
- Your own statewide record: a request to the Bureau of Criminal Apprehension.
