In all actions for the violation of an ordinance, the first process shall be a summons, but a warrant for the arrest of the offender shall be issued upon the sworn complaint of any person that an ordinance has been violated and that the person making the complaint has reasonable grounds to believe the person charged is guilty of such violation. Any person arrested under a warrant shall be taken without unnecessary delay before the proper officer to be tried for the alleged offense.
