Who carries out investigation for election-related criminal offenses?

Algeria
المادة 16: يمارس ضباط الشرطة القضائية اختصاصهم المحلى فى الحدود التى يباشرون ضمنها وظائفهم المعتادة
Source: Article 16, Algerian code of criminalprocedure (adopted on 08.06.1966).
The mentioned article here is very general but this isreturned to the fact that election law was issued on 2012 and without anyspecific regulations for investigation and prosecution.
