Shearman & Sterling is expanding its international white collar crime practice by taking on Connecticut's top federal prosecutor for the New York office.
Stephen Robinson will become a partner in the litigation group, specialising in white collar criminal defence work and client-related internal investigations.
Before becoming a US attorney, Robinson was chief compliance officer at Aetna Healthcare, and before that he was principal deputy general counsel at the Federal Bureau of Investigation (FBI).
While he was head of the US Attorney's office for the District of Connecticut, he was in charge of 50 attorneys in three offices, with a remit of setting prosecution guidelines and policies for all criminal and civil matters.
Joint head of Shearmans' litigation group Henry Weisburg says: "Stephen has fabulous experience in both white collar crime and also as a result of a number of his prior career spots in international investigations. He's a very sophisticated supervisor of multijurisdictional investigations, which we think is a real value that is increasingly in demand.
"We're doing more and more of that work, and we'd like to be doing even more. I think there's more of this type of work around and we expect it to expand substantially and also expand globally."
He says Shearmans is already doing this type of work across Europe and the US, and has also handled significant internal investigations in Asia and Latin America.
The litigation practice boasts 140 lawyers and is regularly involved in M&A, anti-trust, securities, intellectual property and international arbitration work.
