Longville Police Department (merged / disbanded)

This changed. Longville no longer has its own police department. Cass County's official Sheriff's Office 'Patrol' page states the Sheriff's Office 'contracts with 3 communities (Cass Lake, Backus and Longville) for law enforcement and patrol services.' 'Longville Police Dept.' does not appear on the Minnesota POST Board's current (2026) roster of licensed agencies, corroborating that no independent department is active. Coverage is now Cass County Sheriff's contract patrol, 218-547-1424.
