Finding Someone in Custody in Mandeville
A person kept in custody after an arrest in Mandeville is held at the parish jail, run by the St. Tammany Parish Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the St. Tammany Parish Sheriff's Office at inmates.stpso.revize.com/bookings (page title: St. Tammany Parish Sheriff Office 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.
