Officers are then deployed to those areas, which cover a radius of no more than 250 yards, to act as a deterrent or even catch the villain in the act.

Analysis suggests the computer algorithms are ‘seven times more accurate than chance’. A pilot scheme saw ‘significant reductions’ in burglaries in Hackney, Wandsworth, Newham and Lewisham.

Met Commissioner Sir Bernard Hogan-Howe now wants to use the technology to tackle antisocial behavior and vehicle crime and extend its use across the capital.

The system was developed in America from the same kind of calculations used to predict earthquakes.
