Finding Someone in Custody in Isanti County
A person kept in custody after an arrest in Isanti County is held at the county jail, run by the Isanti County Sheriff's Office, whichever agency made the arrest.
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 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.
