A former Bank of New York employee pleaded guilty to charges stemming from a $7-billion Russian money-laundering scheme in a plea deal that calls for several months of home confinement. Svetlana Kudryavtsev, 50, of Brooklyn, N.Y., entered the plea in U.S. District Court in Manhattan. She will be sentenced July 7. Kudryavtsev, who was an associate in the bank's Eastern European division, admitted accepting $500 a month to monitor accounts being used to launder money. Last month, Lucy Edwards, the bank's former vice president in the Eastern European Division, and her husband, Peter Berlin, pleaded guilty in the case and named Kudryavtsev as part of the scheme.
