A dozen patients are suing North Shore-Long Island Jewish Health System for allegedly failing to protect their medical records and notifying them of a theft, CBS New York reported. The class-action lawsuit claims patients' face sheets with names, addresses, Social Security numbers, dates of birth and medical histories were stolen since 2010 from North Shore University Hospital. The plaintiffs' attorney says thousands of other former patients may have had their information compromised too, Long Island News 12 reported. The suit alleges hospital workers (who still work there) were involved in an identity theft ring; two people have been arrested in connection with the alleged fraud.
