When Maqsood Lodin, 22, was being interviewed by police in Berlin, security discovered a memory card in his underwear.
It raised suspicions, but on first glance only appeared to contain the movie Kick Ass and a bunch of pornographic movies.
Upon further inspection (no one knows how much of the porn investigators had to watch) it was discovered one film was actually encoded with more than 100 secret al Qaeda documents.
Al Qaeda planned to hijack cruise ships and post footage of passengers being executed online tin a bid to pressure governments to release prisoners.
The document also showed how the terror network wanted to dress tourists up in Guantanamo Bay-style orange jumpsuits before murdering them.
There was also information about the London 7/7 and 21/7 bombings. It also explained how and how counter-surveillance measures by the 21/7 bombers threw security officers off their scent.
The files also contain details of the ways al Qaeda learns from its mistakes, and the levels of sophistication and determination within its ranks.
In addition, they reveal the impact that military drone strikes and infiltration by intelligence agencies are having on the group’s numbers and behaviour.
