Harry Markopolos, the man who waged a decade-long campaign to blow the whistle on fallen money manager Bernard Madoff, has told the US Congress that he had feared for his safety. Markopolos also assailed the Securities and Exchange Commission, accusing it of "roaring like a lion and biting like a flea".

The SEC failed to act despite receiving credible allegations of fraud from Markopolos about Madoff's ponzi scheme since 2000. Due to the agency's inaction, "I became fearful for the safety of my family," said Markopolos.
