Embedded Player NPR's Julie McCarthy reports from London that British police foiled a plot to steal 500-million-dollars worth of diamonds from a display in the Millennium Dome. The robbers threw smoke bombs as they crashed into the Dome on a bulldozer this morning. Acting on a tip-off, dome officials had replaced the jewels -- including the spectacular 203-carat De Beers Millennium Star -- with fakes. Police arrested 12 people after the attempted heist -- which would have been the world's biggest robbery, if successful.
