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

That page is the office's jail information page rather than a roster, so a search for a particular person goes through the office at (530) 283-6267.
