A fraud unit investigator may execute an arrest warrant and search warrant for the same criminal violation; serve subpoenas issued for the examination, investigation, and trial of all offenses identified through an investigation; and arrest upon probable cause without warrant a person found in the act of committing a violation of the provisions of this chapter.
