In England, thieves are using wireless bluetooth technology to steal cell phones and laptops from cars, according to a report in the Manchester Evening News on June 16. Bluetooth is the wireless system that allows short-range communication between devices. When a thief passes a car with bluetooth electrical items, a signal appears on the screen of the thief’s mobile displaying the make or model of the valuables inside. Police say advanced technology in mobile phones is behind a steep rise in vehicle crime in south Manchester, according to the Evening News report. In one area police estimate that out of the last 35 vehicle crimes, at least 20 involved the use of a bluetooth-enabled phone. Local police are urging drivers to make sure the devices are switched off. Other security experts recommend disabling the infrared and bluetooth ports on the laptop to prevent others from browsing files.
