MIAMI AP – A wealthy accountant who provided extensive help in the tax evasion probe of Swiss bank UBS AG was sentenced to a year of house arrest Wednesday after admitting he concealed about $6 million in assets from the IRS.

Steven Michael Rubinstein, 55, was the first U.S. citizen charged in the probe. U.S. District Judge Marcia Cooke said his prosecution sent a message around the globe about the risks of hiding assets in offshore accounts – and that he deserved credit for helping U.S. investigators find more tax cheats and crooked bankers within UBS and other institutions in Switzerland and elsewhere.
