Any municipality in the Czech Republic, no matter how large or small, may decide to establish a Municipal police ( or "Městská policie" in cities) by a local ordinance. Municipal police authority is generally limited to the area of given municipality, however neighboring municipalities may conclude agreement which extends authority of a given municipal police also over its territory (this is usually used by small municipalities located adjacent to large towns in order to save funds). Municipal police department is controlled by the mayor or another authorized member of the municipal council. The emergency phone number of the municipal police is 156.
