French National Police

The National Police (Police Nationale) is the main law enforcement agency of France, the other main one being the Gendarmerie. It is run under the Ministry of the Interior and has about 150000 employees.

The National Police and the Gendarmerie have sole competency for arresting suspects, serving search warrants, and conducting enquiries (under the supervision of the judiciary). In some cases, customs officers may also have those competencies.

Local police forces operated by communes (cities and towns) do not have legal powers beyond traffic law enforcement and the normal citizen's arrest power that all persons have. Whether or not they should be allowed to carry firearms is a disputed issue.

Organization

The police is divided into directorates [1]: Security in the Paris area is the domain of the Paris Prefecture of Police.
