Note that the defendants are not said to be in custody. I take it then that they are not.

Swiss Banking Executive and Swiss Lawyer Charged with Conspiring to Defraud the United States
Defendants Aided Wealthy Americans Conceal Assets in Secret Swiss Bank Accounts
WASHINGTON - Hansruedi Schumacher and Matthias Rickenbach, both of Switzerland, were indicted today for conspiring to defraud the United States, the Justice Department and Internal Revenue Service (IRS) announced. According to the indictment, Schumacher worked as an executive manager at Neue Zuercher Bank (NZB), a Swiss private bank located in Zurich, Switzerland. Rickenbach worked as a Swiss attorney who provided legal advice and services to U.S. clients. Both are alleged to have aided wealthy Americans conceal assets and income in Switzerland from United States authorities.
According to the indictment, Schumacher and Rickenbach helped wealthy American clients conceal their assets by establishing sham and nominee offshore entities to hide their U.S. clients' assets and income while allowing these clients to still control the assets and make investment decisions.
The indictment further alleges that Schumacher and Rickenbach regularly traveled to the United States to conduct banking and investment activities with their U.S. clients and that when they traveled they concealed their business activities in the United States by falsely representing to American authorities that they were traveling to the U.S. for personal reasons. While in the United States, the defendants would sometimes bring cash for their clients.
According to court documents, Schumacher and Rickenbach aided their wealthy American clients repatriate money back to the United States using several deceptive means. Schumacher and Rickenbach helped their clients obtain offshore credit cards and created sham loan documents. Additionally, Schumacher and Rickenbach falsified bank documents to generate the appearance that assets of their U.S. clients belonged to Swiss citizens, and they falsified documents to disguise their United States clients' repatriation of offshore funds as inheritances from foreign citizens.
According to court documents, Schumacher and Rickenbach discouraged their U.S. clients from voluntarily coming into compliance in the United States. Instead, the defendants encouraged their clients to transfer their assets from UBS, a large Swiss bank, to NZB, a smaller bank in Switzerland. The defendants told their clients that their assets and identification would be safer at NZB because they had no presence in the United States and was therefore less likely to be pressured by the American authorities to disclose the identities of their United States clients.
