Devices that gather data from millions of mobile phones are being flown over the US by the government, according to the Wall Street Journal.
The “dirtbox” devices mimic mobile phone tower transmissions, and handsets transmit back their location and unique identity data, the report claims.
While they are used to track specific suspects, all mobile devices in the area will respond to the signal.

The department said that it operated within federal law.
