Bogus Aircraft Distress Call Results In Two Arrests

No proof that any aircraft was ever in distress.

MEDICINE HAT, Alta. — Police in southern Alberta have arrested two people as part of an investigation into a bogus aircraft emergency distress call.

Medicine Hat police say they have two adults in custody but there was no immediate word on charges.

The alleged false radio distress call Sunday night prompted officials to close part of the Trans-Canada Highway temporarily for a possible emergency landing.

The Royal Canadian Air Force also dispatched a CC-130 Hercules search and rescue aircraft from a base in Winnipeg to investigate.

No contact was made with a pilot, there were no official reports of a missing plane and no wreckage of a downed aircraft has been found.

Saskatchewan RCMP say a work crew near Maple Creek heard muffled audio of a Mayday distress call over their handheld radio and called police.
