The director shall appoint such law enforcement officers as he deems necessary for the proper enforcement of law and the providing of police protection within the county. All officers regularly appointed shall be qualified under the provisions of Kan. Stat. Ann. § 74-5601 et seq., but an officer may receive a temporary appointment pending his completion of the requirements for a certificate thereunder. The agency shall determine and fix such additional minimum qualifications to be required of persons appointed as law enforcement officers as they may deem necessary, and may provide for the examination of applicants therefor. Law enforcement officers appointed under the provisions of this act shall be responsible to and may be suspended or removed by the director for cause. The director, within twenty-four (24) hours thereafter, shall report such suspension or removal and the reason therefor to the agency who as soon thereafter as possible, shall fully hear and determine the matter and affirm or revoke such suspension or removal.
