In the video you will notice a rescued man clinging to the police escort. How does this happen? Some were held for 15 years. Some have escaped and tipped the police, which started the investigation. Apparently a new law was needed in Britain to make holding a person against their will, against the law. Offenders face 14 years in prison. Miserably light sentence, in my opinion.
