Finding Someone in Custody in Warren County
A person kept in custody after an arrest in Warren County is held at the county jail, run by the Warren 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 518-743-2500.
