Andy Robertson, an escape artist whose specialty is escaping from locked prison cells, offers an insight into getting out of "impossible" situations…

Prison escapes in the UK are rare – but then how have so many prisoners over the years escaped out of seemingly high-security prisons all from the UK and other parts of the world? That’s the question that intrigued me, I had to know how they were getting out and whether it was by flaws in security, or skill, or just plain luck! 

Over many years I studied locks and doors used as well as the old and modern type prison and jail buildings. I spoke to many people from prison historians to those who were presently in the profession linked to prison security.  I also learned the skills and knowledge as an escape artist over many years from fellow escape artists, finally in 2017 I had the ability to escape any prison and I was soon to be challenged to prove it.
