Where a person acting as a pedlar either refuses to show his certificate or has no certificate, or refuses to allow or prevents, or attempts to prevent any such opening or inspection of his pack box, bag, trunk, or case as is authorised under this Act, it shall be lawful for any of the persons authorised to demand the production of the certificate, and also for any other person acting by his order or at his request and in his aid, to apprehend such offender, and forthwith to convey or cause him to be conveyed before a justice of the peace. In Scotland such justice of the peace may commit such offender for trial if he think fit.
