US prosecutes '$6bn money-laundering hub'
The Liberty Reserve digital money service that was shut down laundered more than $6bn (£4bn) in criminal cash, US authorities have said.
Weekend police raids in 17 countries scooped up Liberty Reserve's owners, operators and its computer hardware.
The Department of Justice said it was the "largest international money-laundering prosecution in history".
