WINNIPEG — WestJet says six passengers sustained ******** during an ********* ********** when one of its flights was diverted to Winnipeg on Monday night due to what the company has only termed “a ******.”

The company said all 54 passengers and five crew on Flight WS422 from Edmonton to Toronto were evacuated from the plane shortly after landing.

“The flight crew, in conjunction with our Operations Control Centre, made the decision to divert the aircraft to Winnipeg James Armstrong Richardson International Airport,” Robert Palmer, a public relations spokesman for the company, said in an emailed statement.

“In order to ******** the aircraft as quickly as possible, the crew made the decision to deploy the ********* ********** slides. Initial reports indicate six guests received non-life threatening ******** during the ********** and were treated by ********* response officials on the ground.

“A number were taken to hospital for further treatment, accompanied by members of WestJet’s Special Assistance Team.”

Palmer described that team as “WestJetters who have regular jobs with the ******* but who volunteer to receive specialized training to help guests in the event of emergencies.”

The company said after being interviewed by ******, passengers would be put up in local hotels for the night and they would be put on flights to Toronto the next morning.

********* vehicles dotted the tarmac after the plane landed. As passengers slid down ********* chutes, they were loaded onto buses to be transported to the terminal.

The company would not provide details on the nature of the ****** but said late Monday that the plane had been searched and cleared to go back into service following routine maintenance.

“We will not address anything that will be part of the ****** *************,” said Palmer.

It’s the third ****** involving a flight in the last week.

A WestJet flight from Edmonton to Halifax landed in Saskatoon after a ****** Saturday morning.

****** said a call had been made claiming an ********* 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 **** ****** on an ********** flight.

The airport authority said it took the action after ********** Flight 143 departing from St. John’s to Ottawa was notified about a possible **** 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 **** ****** was found in one of the plane’s washrooms.

Nothing suspicious was found in a search of the plane.
