An electronic cigarette was to blame for a terror alert that closed the M6 toll road for more than four hours.
Bomb disposal experts and counter-terrorism officers were scrambled to the motorway near Lichfield after a passenger on the Megabus service from Preston to London reported seeing vapour coming from a man's bag at around 8am.
The 48 passengers were led from the coach and walked about 300 yards to a cordoned-off area on a closed carriageway. Witnesses described how they came off the coach “one by one holding their arms up” to prove they were not armed. They were then searched by officers.
Initial reports suggested a passenger had been spotted pouring liquid into a bag, which was giving off fumes.
