No holder of any unexpired license certificate issued pursuant to this chapter shall knowingly employ in connection with his business in any capacity whatsoever any person who has been convicted of a felony, who has been discharged from a law enforcement agency for cause, whose private detective license was revoked or application for such license denied by the authorities of this city or any other city or state or who has been found guilty of illegally using, carrying or possessing a pistol or other dangerous weapon, buying or receiving stolen property or any offense indicating moral turpitude. Should the holder of an unexpired license certificate falsely state or represent that a person is or has been in his employ, such false statement or misrepresentation shall be sufficient cause for the revocation of such license. Any person falsely stating or representing that he is or has been a detective or employed by a detective agency, shall be guilty of a misdemeanor. (Ord. 4039)
