When it says the coach pulled over of its own accord, does this mean it got pulled over by police ? or that it was just found idle on the hard shoulder...
and how on earth did they know explosives may be on board this story is really interesting.
I think what it means, is passengers saw "dodgy guy" with smoking bag. Driver notified, police notified, driver pulls over and police raid bus. Probably over something stupid.
But still at least we aren't American, I couldn't believe the security over there, it's like the terrorists have allready won and they've sacrificed they're lives in the big cities (NyC & Washington).
