LOS ANGELES: Paris Hilton made an appearance in federal court for the sentencing of a hacker who authorities say used her bank and credit card information to run up huge bills. Paystar Bkhchadzhyan (buk-CHAHD’-zhee-ahn) was sentenced to four years and nine months in prison Monday and was ordered to pay more than $318,000 in restitution to Hilton’s banks and credit card companies. In a deal with prosecutors, she pleaded guilty in November to conspiracy to commit bank fraud. In an unusual move in such cases, the 37-year-old heiress showed up at the downtown Los Angeles courthouse in a business suit and sunglasses to give a victim impact statement. Authorities said in charging documents that the defendant also stole nude photos of Hilton, but the pictures were not part of the plea.
