Finding Someone in Custody in Cumberland County
A person kept in custody after an arrest in Cumberland County is held at the county jail, run by the Cumberland County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Cumberland County Sheriff's Office at inmates.cumberlandcounty.revize.com/bookings (page title: Inmate Locator | Cumberland_County_ME_Inmates_App), 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.
