A man was arrested and held in police cells for seven hours as a suspected terrorist after making a joke on Twitter about blowing his local airport sky high. Paul Chambers, 26, tapped out the comment to amuse friends because his planned trip to Ireland was under threat due to heavy snow at Robin Hood Airport in Doncaster. ‘C**p! Robin Hood Airport is closed,' he tweeted. ‘You've got a week and a bit to get your s*** together, otherwise I'm blowing the airport sky high!!'. But a week later, police arrived at the finance superviser's office to arrest him under the Terrorism Act – after an apparent anonymous tip-off.
