Law-abiding citizens could be under surveillance via their mobile phones as Met police introduce a new phone-tracking technology, it was revealed today.
Police can now shut off phones remotely, listen in on conversations and gather data about users in a targeted area – even innocent members of the public.
The Met would not confirm whether the system has yet been used in public disorder situations, such as the London riots or protests at St Paul’s and Parliament Square.
The Met bought the system from Datong plc in Leeds, which serves the US Secret Service, the Ministry of Defence and regimes in the Middle East, according to a report in The Guardian.
The news has provoked alarm among lawyers and privacy groups that innocent people could become unwitting targets.
