First Facebook investigation to be completed by summer

Facebook’s lead regulator in the European Union expects to conclude the first of seven investigations into the company’s use of personal data this summer and the remainder by the end of the year, Ireland’s Data Protection Commissioner said on Thursday.

The commissioner’s office last year launched three investigations into aspects of a massive cyber attack in which hackers stole login codes that allowed them to access nearly 50 million Facebook accounts, including 3 million in Europe.
