Caught on Tape: Dirty Sexy London Heist

Security camera footage released by police Tuesday shows two men in crisp suits entering Graff Diamonds' flagship store Thursday afternoon. It was the third time a Graff store in London had been targeted in a high-profile raid in the past six years.

The men stole dozens of high-end rings, bracelets, necklaces and watches worth 40 million pounds, or $66 million, and fired two gunshots into the ground as they escaped in a series of getaway cars, police said. No one was hurt.

It was among the biggest heists in British history — far outstripping the 1963 Great Train Robbery in which 2 million pounds were lost.

Last week's theft, however, was topped by the 2006 robbery of 53 million pounds in cash from a security company depot in southern England, and was rivaled by the 1987 theft of an estimated 40 million pounds from the Knightsbridge Safe Deposit Center in London.

Police declined to rank Thursday's robbery, saying only that it was one of the country's biggest. Items stolen included a pair of white diamond double hoop earrings, a flowing flower necklace with yellow diamond petals, a platinum white Marquise diamond ring and a Chronograff watch, police said.

Graff's store, a classical stucco and stone town house in London's jewelry district, has been targeted by thieves in the past.

The same store lost jewelry worth 23 million pounds in 2003 when it was robbed by jewel thief Nebojsa Denic, a Kosovan Serb and a member of the notorious gang of Balkan robbers known as "the Pink Panthers." Denic was caught and sentenced to 15 years in prison.

In 2007, another smartly dressed pair was chauffeured to the store's Sloane Street branch in a Bentley Continental Flying Spur. They whipped out handguns and made off with 10 million pounds worth of gems.

Graff Diamonds declined to give details beyond the police statement.
