The hunt for money hidden in Swiss bank accounts by U.S. citizens has become a global chase, with prosecutors tracing records to Singapore, the Cook Islands and elsewhere as U.S. authorities increase the pressure on Swiss lenders to turn over evidence, the Wall Street Journal reported today. Kathryn Keneally, head of the Justice Department's tax division, said that in the wake of a guilty plea to criminal charges by Credit Suisse Group AG , the U.S. expects to collect more evidence pointing to suspect accounts beyond Switzerland's borders. Credit Suisse, which last week pleaded guilty to conspiracy and agreed to pay $2.6 billion to settle allegations it helped wealthy Americans hide money from the Internal Revenue Service, has agreed to turn over some bank records that can help U.S. authorities track down individual account holders across the globe.
