There was yet another bomb threat to a WestJet flight, the fifth one in the past six days, forcing authorities to do a thorough search of the aircraft.

WestJet said Flight 1709, travelling from Las Vegas to Victoria, received the threat in mid-air on Thursday evening.

Confirm YYJ received bomb threat against our aircraft #WS1709. Worked with regulatory & law enforcement agencies and deemed not credible. — WestJet (@WestJet) July 3, 2015

The aircraft was allowed to complete its flight landing safely in Victoria where a precautionary screening was conducted. The plane was searched by bomb-sniffing dogs and no explosives were found.

Screening on #WS1709 was done out of an abundance of caution. Aircraft has been cleared. RCMP to proceed w/ criminal mischief investigation. — WestJet (@WestJet) July 3, 2015

WestJet said the RCMP is now involved, investigating for criminal mischief.

This week’s false threats are all criminal investigations, and we will support investigators as they seek out those responsible. — WestJet (@WestJet) July 2, 2015

Officials told the CBC that they are not treating this as a credible threat with no explosives being found on the plane.

The five threats have been declared hoaxes.
