A former associate at US firm Ropes & Gray has been identified as a key player in the Galleon Group insider trading probe, reports The Am Law Daily.

Former Ropes intellectual property associate Brien Santarlas pleaded guilty last Thursday (10 December) to stealing information about firm clients and passing that information on to other sources for insider trading purposes.

Another former Ropes associate, Arthur Cutillo, was charged last month for providing traders with inside tips about three private equity transactions on which Ropes was advising. He has pleaded not guilty to the charges.
