Glendale, CA police have arrested Ara Gabrielyan, 32, a man they say tracked his ex-girlfriend’s whereabouts by attaching a global positioning system to her car. Police said Gabrielyan attached a cellular phone to the woman’s car on August 16 with a motion switch that turned on when the car moved, transmitting a signal each minute to a satellite. Information was then sent to a Web site that allowed Gabrielyan to monitor the woman’s location.
