Law enforcement in the Czech Republic is divided between several agencies. The main agency is the Police of the Czech Republic with general vested authority limited only in areas of operation of other authorities. State Agencies Municipal police Any municipality in the Czech Republic, no matter how large or small, may decide to establish its own Municipal police ( or Městská policie in cities) by a local ordinance.
