The Securities regulator of the State of Massachusetts filed a complaint against Citigroup Inc. (NYSE:C), for Mahaney’s misconduct in disclosing confidential information.

The junior analyst works under Mahaney.  Citigroup Inc. (NYSE:C) fired the junior analyst on September 27.

The Massachusetts Securities Division found out the misconduct of the Mahaney and his junior analysts through the e-mails sent to TechCrunch employees and to the French journalist.

The securities regulator alleged that Citigroup Inc. (NYSE:C) failed to supervise Mahaney and his junior research analyst, which allowed their dishonest and unethical practices in the securities business, and the company was ordered to pay $2 million in fines. In a statement, Massachusetts Secretary Gavin said, “This penalty should serve as a warning to the industry as a whole.”
