The jewel thieves who police say ripped off Cartier's Midtown store are now being linked to several other robberies along the east coast.
Last month, Allen Williams and Roberto Grant - both from Brooklyn - were arrested on the same day police say they smashed up a Midtown jewelry store and made off with $700,000 worth of watches.
They're facing charges including robbery and grand larceny.
Now, prosecutors are saying they pulled off similar robberies at jewelry stores in New Jersey and Virginia - the first one was back in July.
Two other men have also been arrested and accused of being involved in all four robberies.
