Oak Grove, Minnesota, in Anoka County, has about 9,300 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 County Attorney files charges, a case in the Anoka County District Court. 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 Oak Grove
The FBI lists no arrest reporting agency under the name of Oak Grove. In Anoka County the county agency that reports arrests is the Anoka County Sheriff's Office.
Booking: Where People Arrested in Oak Grove Are Held
The county jail is where a person arrested in Oak Grove 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 2019 the jail held about 310 people. Its rated capacity in 2019 was 478 beds, and it ran at 65 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 Oak Grove
An arrest in Oak Grove can be traced in two places, depending on where the case stands: 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 anokacountymn.gov/4175/County-Attorneys-Office, phone 763-324-5540).
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 Oak Grove
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.
