The Globe and Mail reports in its Friday edition that Quebec provincial police say one man could face fraud charges after a security incident prompted the deployment of fighter jets to escort two passenger flights into the Montreal airport on Wednesday. The Globe's Maura Forrest writes that two Canadian men on Air Canada flights from overseas were arrested in Montreal after the incident prompted the NORAD to scramble CF-18s, F-16s and KC-135s, which are aerial refuelling tankers, to accompany them. Authorities have not confirmed the details of what prompted the response, but one expert says it's "quite rare" for jets to be deployed to protect commercial airlines. Sûreté du Québec said that both men have been released pending further proceedings, adding that the investigation was continuing and had not yet been referred to Quebec's public prosecution service, which would decide whether to lay charges. Defence Minister David McGuinty confirmed on Thursday that "NORAD jets were scrambled and the matter is under active investigation." He said it would be up to law enforcement to determine what took place. Air Canada confirmed that "heightened security measures" at the Montreal-Trudeau airport were related to two flights.
