WestJet flight safely diverted to Winnipeg over unspecified threat

WINNIPEG - WestJet says one of its flights has been diverted to Winnipeg due to what the company termed "a threat."No details on the threat were immediately available, but the company sent out a Tweet saying all 54 passengers and five crew on Flight WS422 from Edmonton to Toronto had been evacuated from the plane shortly after landing.It's the third threat involving a flight in the last week.A WestJet flight from Edmonton to Halifax landed in Saskatoon after a threat Saturday morning.Police said a call had been made claiming an explosive device was on board but the report turned out to be false.Last Thursday, St. John's International Airport was temporarily closed because of a bomb threat on an Air Canada flight.The airport authority said it took the action after Air Canada Flight 143 departing from St. John's to Ottawa was notified about a possible bomb on board at about 6:50 p.m. as the aircraft was pulling back from the gate.Royal Newfoundland Constabulary spokesman Steve Curnew told reporters early Friday that the flight was about to leave when a note identified as a possible bomb threat was found in one of the plane's washrooms.Nothing suspicious was found in a search of the plane.(CJOB, The Canadian Press, CTV News)
