Ayub Qassim, a convicted drug dealer, is revealed to be the mystery man 'Johnny Vegas' involved in the disappearance of teenager Jay Slater in Tenerife. Jay vanished after staying at an Airbnb with Qassim and another man, with extensive search efforts near the last location of his mobile phone yielding no results. Qassim, previously jailed for drug offenses, admitted providing shelter to Jay before his disappearance, but Spanish police considered them 'irrelevant' to the investigation. Former Met Police officer Mark Williams-Thomas interviewed Qassim, extracting details about Jay's last moments, shedding light on the case's mysterious circumstances.
