(Shutterstock) (Newser) – A man in Greece has been arrested on suspicion of having stolen 9 million personal data files in what is believed to be the biggest breach of private information the country has ever seen. Police said today that the 35-year-old, whose name was not released, was found in possession of the data files that included identity card details, tax numbers, vehicle license plate numbers, and home addresses. If all the victims are Greek, the theft could encompass roughly 90% of the country's population. But the files appeared to include duplicate entries, meaning the number of individuals affected could be lower. Authorities are investigating how the man, who faces felony charges of data theft, came into possession of the files and whether he intended to sell the list.
