Finding Someone in Custody in Cumberland County
The county jail, run by the Cumberland County Sheriff's Office, holds everyone kept in custody after an arrest in Cumberland County, from every agency.
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.
