Electronic cigarette causes terror alert WEEFORD, England, July 5 (UPI) -- Police said a passenger's electric cigarette caused a terror alert that prompted officers to stop and board a London-bound bus Thursday. The security alert, which led to the closure of the M6 motorway, started after a passenger called police around 8:20 a.m. and reported seeing vapor seeping out of another passenger's bag. The bus was stopped at Weeford, where police escorted passengers off the bus and closed the road for more than 4 hours, The Independent reported. "The information received concerned a report of vapor escaping from a bag which on investigation turned out to be a health improvement aid for smokers," a police spokeswoman said. It is important to state that no criminal offense has been committed and no passenger or any other member of the public is being treated as a suspect.
