The six City figures who were arrested in March by the Financial Services Authority (FSA) and the Serious Organised Crime Agency (SOCA) have seen their assets unfrozen after a series of agreements were granted by a judge in the Southwark County Court.
Some of the six have offered property assets of up to £1m, while it is understood that others have agreed to a £4m security deposit.
The judge had turned down two previous requests to have the freeze lifted.
The list of City workers arrested included Clive Roberts of Exane, Martyn Dodgson of Deutsche Bank, Julian Rifat of Moore Capital, Graeme Shelley of Novum Securities, stockbroker Ben Anderson and businessman Iraj Parvizi.
Rod Fletcher at Russell, Jones & Walker is representing Roberts, while Ian Burton of Burton Copeland is acting for Shelley.
Other lawyers retained on the matter include Stephen Pollard, Matthew Jenkins and Michael Potts.
