The Post reports that a pair of Bulgarian nationals accused of getting bank account information from 1,500 unwitting debit card users (and bilking them out of $300,000) pleaded not guilty today. According to prosecutors, Dimitar Stamatov, a limo driver, and Iordan Ivanov, a mechanic, set up pinhole cameras and skimming devices at four Chase bank ATMs around Union Square and Astor Place.
