(C) A peace officer who seeks to cause an arrest or prosecution under this section may file with a reviewing official or the clerk of a court of record an affidavit charging the offense committed.

(D) A private citizen having knowledge of the facts who seeks to cause an arrest or prosecution under this section may file an affidavit charging the offense committed with a reviewing official for the purpose of review to determine if a complaint should be filed by the prosecuting attorney or attorney charged by law with the prosecution of offenses in the court or before the magistrate. A private citizen may file an affidavit charging the offense committed with the clerk of a court of record before or after the normal business hours of the reviewing officials if the clerk's office is open at those times.
