Tom's Guide tested an incongruous object: a cell phone jammer hidden in a pack of cigarettes.

The roof of their laboratory vehicle is equipped with a radio direction finder, a device that can locate the direction of the transmitter and direct them to a building in Clermont. Six elite police officers from the Belt and Road (Research and Intervention Team) then intervened.
