(a) No disclosure shall be made to any law enforcement official, including any public prosecutor, without the specific written consent of the individual except as is necessary under section 7143(a)(7). However, nothing in these regulations shall be construed as prohibiting an employee of the Department from seeking the assistance of a law enforcement official where an individual commits or threatens to commit a crime on the premises of the Department or against Departmental personnel, or where an individual, after investigation, is reasonably believed to have committed a fraudulent or otherwise illegal act or acts against the Department or Departmental personnel, and such disclosure is made for purposes of further investigation and/or prosecution for such act or acts. Nothing in this section shall be construed to allow the disclosure of information to law enforcement officials, including public prosecutors, for purposes of investigating or prosecuting illegal acts allegedly committed against a third party or entity, except as necessary under section 7143(a)(7).
