Criminal actions and proceedings for a violation of the provisions of this chapter shall be commenced and prosecuted in the district court for the district within which the offense was committed, and when not committed within any judicial district, then in the district court for the district within which the offender may be found; and suits of a civil nature may be commenced in the district court for any district within which the defendant may be found and shall be served with process.
