In towns and cities across the UK, the wealthy are being watched. Organised criminal gangs are targeting millionaires, high-profile sports stars and some of Britain’s most exclusive jewellery stores. Not randomly. Not recklessly. But with precision.

They research their targets. Track their movements. Study alarm systems. Map escape routes. Then they strike. Safes are ripped out in minutes. Priceless jewellery displays cleared before police even arrive. Millions in watches, diamonds and cash disappearing into criminal networks that stretch far beyond Britain’s borders.

So who are these criminal gangs? How do they choose their targets? And where does the money go?
