The Mounties have warned every police agency in the country about cellphone jammers after two Quebec officers were left with two suspects and dead radios on a darkened highway shoulder last month. It was Oct. 15 and the Quebec City police officers had stopped a car whose occupants they believed were connected with organized crime. When they approached the car, they saw “a suspicious device” on its door, police sources said. The suspects told police they bought the “jammer” — which sends out a powerful radio signal that makes it impossible for phones within a 10-metre radius to communicate with cell towers — on eBay. The officers seized the jammer and alerted their criminal intelligence section. That section alerted the Cornwall integrated criminal intelligence section which sent the officer safety bulletin nationwide on Oct. 29.
