Old thread I know but for anyone who is interested I actually know a lot about this as I worked there at the time!
Barry McKenna was the dealer involved, he was caught on the casino security camera taking the marked cards out of his socks.  The casino fired him & walked him out but unfortunately this was before they called the police. On investigation he had been doing this for months and  he admitted to a friend he was getting 10% of all the “winnings” from Billy the Egyptian. He claims to have racked up over &10,000 which he even bought a car with however the majority of his money went on cocaine as he had a serious addiction which got him into thousands of debt (this is actually the reason WHY he got involved in the scam- to help pay drug debt). Within days he flew out to Lanzarote leaving behind 6 kids who he has never spoken with or seen since. There is a warrant out for his arrest so he is too big a shite bag to fly into the uk. I had him on Facebook, he works in the Devon Bar in Puerto Del Carmen living a great life which is a major kick in the teeth to those he stole from. And a kick in the teeth to his children too.
