It shall be lawful for the director, or for any agent of the director, to detain any package containing or supposed to contain such alcoholic liquor when he has reason to believe that the tax imposed by law upon the same has not been paid in full, or that the same is being or has been removed from any bonded warehouse, or has been received and transported into the state of Kansas in violation of the law; and every such cask or package may be held by him at a safe place until it shall be determined whether the property so detained is liable by law to be proceeded against for forfeiture; but such summary detention shall not continue in any case longer than forty-eight hours without process of law.
