British police charged a man with attempted murder Saturday in connection with a $65 million jewelry robbery in London last month.

Aman Kassaye, 24, faces the most serious charge so far in the Aug. 6 robbery of Graff Diamonds. Six other men have already been charged with conspiracy to rob the prestigious Bond Street jeweler of diamond rings, bracelets, and watches.

Amateur video shot outside the store appeared to capture the aftermath of the robbery and images of screaming shoppers ducking for cover as a shot is fired. No one was hurt in the robbery, one of the biggest in British history.

Security camera footage released by police shortly after the theft showed two men in suits being let into the store, where police say they pulled out guns, briefly took an employee hostage and escaped in a series of getaway cars across central London. Police said at the time they believed others helped the pair escape.

A British newspaper reported last month that the men were wearing stick-on prosthetic faces made from liquid latex. Police have refused to comment on the claim and declined to say whether any jewelry had been recovered.

Besides attempted murder, Kassaye is charged with conspiracy to rob, unlawful imprisonment, and using a handgun to avoid arrest. He was due to appear at a London court Monday.
