In the past, kidnapping used to be a gang-on-gang phenomenon, but now one-in-five kidnappings involve innocent members of the public.
In this gripping 30-minute documentary, Livvy Haydock meets three kidnap victims from around the UK, who describe their ordeals at the hands of their captors.
For a true insight into this growing and terrifying crime, Livvy tracks down and interviews some of the gang members who orchestrate and plot these vicious attacks, which often include the torture of their victims.
Livvy also speaks to David Jones, the Head of the Kidnap Unit at the National Crime Agency for an exclusive insight into tackling this crime.
