Wickford, Essex - Ryan Cleary, a 19 year old IT buff, 'was just tracking aliens in the IMF' when cops pounced early this morning.
Officers from the Serious & Disorganised Crime Agency seized tin foil hats and laptops in the Essex raid following a tip-off from the FBI.
The operation follows the covert planting of spoiler tracking codes in IMF databanks soon after the arrest of Dominique Strauss-Kahn.
The heavily encrypted trackers hinted that a 'superior female alien clone' - possibly French finance minister Christine Lagarde - is about to blow the lid on EU corruption.
This afternoon the Wickford suspect was being questioned in a lead-lined maximum security police facility - believed to be shopfronted by an innocuous-looking Tooting High Street kebab takeaway.
Cleary's arrest comes amid news updates that Lulzsec hackers have tricked their way into UK 2011 Census records being processed by US defence contractor Lockheed Martin.
