Arrest over speed trap 'jammer'
BBC NEWS
south Wales motorist has become the first person in Britain to be arrested for using an electronic jammer to confuse speed traps.
The driver was found with a laser diffuser device in the vehicle by police in south Wales under a drive called the Safety Camera Partnership.
The gadget, which is also known as a jammer, works by alerting the driver to laser speed detectors and temporarily stopping it from taking a speed reading.
The car had been recorded speeding on six different occasions around Cardiff and the south Wales valleys.
