BBC have reported in 10 o'clock news that the man concerend has now been re-arrested under anti-terrorism laws following questioning at a central london police station. They have 48 hours to charge or release him, but if my memory serves me right, they may apply to the Home Secretary for an extension to hold him for up to one week without charge for further questioning.
All very very embarrassing and concerning for the US. I should think the likes of Virgin and BA will be asking some very very searching questions of the authorities at Washington Dulles.
When will the US finally get its airport security in order?
