Guessing this is the set up they're using ?
Britain's largest police force is operating covert surveillance technology that can masquerade as a mobile phone network, transmitting a signal that allows authorities to shut off phones remotely, intercept communications and gather data about thousands of users in a targeted area.
The surveillance system has been procured by the Metropolitan police from Leeds-based company Datong plc, which counts the US Secret Service, the Ministry of Defence and regimes in the Middle East among its customers. Strictly classified under government protocol as "Listed X", it can emit a signal over an area of up to an estimated 10 sq km, forcing hundreds of mobile phones per minute to release their unique IMSI and IMEI identity codes, which can be used to track a person's movements in real time...
...The company's systems, showcased at the DSEi arms fair in east London last month, allow authorities to intercept SMS messages and phone calls by secretly duping mobile phones within range into operating on a false network, where they can be subjected to "intelligent denial of service". This function is designed to cut off a phone used as a trigger for an explosive device....
...Between 2004 and 2009 Datong won over $1.6 (£1.03m) in contracts with US government agencies, including the Secret Service, Special Operations Command and the Bureau of Immigration and Customs Enforcement. In February 2010 the company won a £750,000 order to supply tracking and location technology to the US defence sector. Official records also show Datong entered into contracts worth more than £500,000 with the Ministry of Defence in 2009....
...All covert surveillance is currently regulated under the Regulation of Investigatory Powers Act (Ripa), which states that to intercept communications a warrant must be personally authorised by the home secretary and be both necessary and proportionate. The terms of Ripa allow phone calls and SMS messages to be intercepted in the interests of national security, to prevent and detect serious crime, or to safeguard the UK's economic wellbeing.
Latest figures produced by the government-appointed interception of communications commissioner, Sir Paul Kennedy, show there were 1,682 interception warrants approved by the home secretary in 2010. Public authorities can request other communications data – such as the date, time and location a phone call was made – without the authority of the home secretary. In 2010, 552,550 such requests were made, averaging around 1,500 per day.
