When an action has been commenced by the filing of a complaint, whether a summons has been executed or not, the plaintiff, his agent, or attorney may, at any time before judgment, sue out an attachment in aid of such action, upon making affidavit and giving bond, as is required in the issue of original attachments, and all proceedings on such attachments must be conducted as are proceedings on original attachments. Such attachment may be sued out in any case in which an original attachment may be sued out and may be issued by the officer having authority to issue original attachments.
