Police forces are being challenged over concerns they are using a controversial snooping technology capable of tracking your every movement via a smartphone.
Rights charity are taking five UK police forces to court over their failure to confirm or deny whether they use the hardware, which mimics cell towers to silently connect with nearby mobile phones to spy on their movements.
These can also be used to intercept text messages and calls without the knowledge of the mobile phone owner.
Cellxion, the Surrey telecoms firm behind the technology, claims the system helps police to combat the growing use of mobile phones by criminals and terrorists.
But privacy experts warn the technology is 'rife for abuse' as it harvests data 'indiscriminately' from nearby cellular devices without consent.
