Blaine County offices and records
Sheriff & Law Enforcement. Blaine County Sheriff's Office is responsible for maintaining law and order in the unincorporated areas of Blaine County.
Police Departments. In addition to Blaine County Sheriff's Office, law enforcement in Blaine County includes the Chinook Police Department and the Harlem Police Department.
Law Enforcement & Arrests. Blaine County Sheriff's Office, headquartered at 400 Ohio Street in Chinook, Montana 59523, is the primary law enforcement agency for unincorporated areas of Blaine County. Inmate information and jail roster details can be obtained by contacting the detention center directly at the Sheriff's Office number or by visiting in person during business hours; currently, Blaine County does not maintain a full online inmate lookup system. Montana public records law, specifically the Montana Constitution Article II, Section 9, and Montana Code Annotated § 2-6-102, guarantees public access to arrest records and booking information. Mugshots and booking photos are considered public records in Montana and can be requested through the same process, though the Sheriff's Office may require in-person pickup or mailed copies as online digital access to mugshot databases is not currently available through county systems.
Arrest Records. They are maintained by the arresting agency, primarily the County Sheriff's Office and municipal police departments.
