Two New York doctors have admitted they took $100,000 in cash payoffs from a medical lab to order lab tests on their patients. Dr. Gary Leeds and Dr. Richard Goldberg told a federal judge in Newark, N.J., that they had accepted the bribes, a U.S. attorney spokesman said Thursday. The arrest of the two doctors now brings to nine the number of physicians who have pleaded guilty in the growing lab scandal. More than a dozen executives and workers with Biodiagnostic Laboratory Services in Parsippany have also pleaded guilty.
