When the complaint served upon an officer is of a criminal nature calling for the discharge of the officer, the chief of the patrol may immediately suspend the officer without pay pending a trial board hearing. The board shall be convened no later than forty-five days from the date of suspension. However, this does not preclude the granting of a mutually agreed upon extension; in such cases the officer shall remain on suspension without pay.
An officer complained of may waive a hearing and accept the proposed discipline by written notice to the chief of the patrol.
