In actions against foreign or domestic receivers holding, owning, claiming, or operating property in this state, the summons and complaint may be executed by the delivery of a copy thereof to the receiver if he is found within the state or, upon affidavit being made by the plaintiff, his agent, or attorney that the receiver cannot be found within the state, then service may be had by leaving a copy of the summons and complaint with any agent in the employ of such receiver; and, if there are two or more receivers of the same estate, firm, person, or corporation, service upon one of such receivers or his agent, as provided in this section, is sufficient.
