The Secretary of the Treasury may apply to a court of competent jurisdiction for a search warrant when the Secretary reasonably believes a monetary instrument is being transported and a report on the instrument under section 5316 of this title has not been filed or contains a material omission or misstatement. The Secretary shall include a statement of information in support of the warrant. On a showing of probable cause, the court may issue a search warrant for a designated person or a designated or described place or physical object. This subsection does not affect the authority of the Secretary under another law.
