Beleaguered Londoners are increasingly having to turn 'vigilante' to 'steal' back their cars from thieves because the Metropolitan Police 'refuse to step in' and help.

Gangs of thieves are seemingly acting with impunity across the capital, brazenly snatching luxury motors or rare vehicles from driveways, garages and off the street.

However, victims claim that even when they have trackers installed in their cars showing where crooks have left them, that police are apparently unwilling to step in.

Owners, frustrated with the 'lack of support' are now turning into detectives - and risking their own safety to find their stolen vehicles and take them back from gangs.

And when victims then do eventually recover their cars, they have claimed officers 'don't have time' to investigate despite a 'slam dunk' of potential forensic evidence.
