Home / California / Mariposa County / Sheriff & police
3 listed agencies make arrests in Mariposa County: the sheriff, city police departments, campus police and state agencies. The arresting agency is usually not the facility that holds the person; the county page has the jail.
Booking, bond and release questions go to the jail, not the arresting agency. Confirm where the person is before you act.
The sheriff is usually the police department for unincorporated areas and the operator of the county jail. An arresting station is usually not the holding facility.

Jail411 lists the public agencies that make arrests so families can find the right door. We are not a government agency, a police department or a live custody-records service.
Often the sheriff runs the county jail, but the jail is a separate facility with its own address, phone and rules. Open the jail page for booking, visiting, mail and money details.
Ask the person, check any paperwork or citation, or call the sheriff's non-emergency line. City arrests belong to that city's police; unincorporated areas and county roads usually belong to the sheriff; freeways usually belong to the state patrol.
The jail can. The arresting agency may confirm an arrest but does not hold the person. Call the jail's booking or information line first.
Send us the page and the detail that needs attention. Include the agency's official page when you have it. Do not send private booking documents or other sensitive personal information.
