(3) Except as provided in subsections (1) and (2) of this section, the notation of arrest shall be removed from the public record as follows:
(a) In the case of an arrest for which no charges are filed as a result of the determination of the prosecuting attorney, the arrest shall not be part of the public record after one year from the date of arrest;
(b) In the case of an arrest for which charges are not filed as a result of a completed diversion, the arrest shall not be part of the public record after two years from the date of arrest; and

(4) Any person arrested due to the error of a law enforcement agency may file a petition with the district court for an order to expunge the criminal history record information related to such error. The petition shall be filed in the district court of the county in which the petitioner was arrested. The county attorney shall be named as the respondent and shall be served with a copy of the petition. The court may grant the petition and issue an order to expunge such information if the petitioner shows by clear and convincing evidence that the arrest was due to error by the arresting law enforcement agency.
