Finding Someone in Custody in Concord
A person kept in custody after an arrest in Concord is held at the county jail, run by the Merrimack County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Merrimack County Sheriff's Office at merrimackcountysheriff.org (page title: Merrimack County Jail Roster Lookup, NH, Inmate Search), a site that blocks automated checks (HTTP 403), so open it in a browser.
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.
