Martin Shkreli pleaded not guilty to securities fraud on Thursday and was released from custody after posting on $5 million bail.

Prosecutors have accused the controversial pharmaseutical boss of running a Ponzi scheme on investors of a hedge fund.

Andrew J Ceresney, director at the Securities and Exchange Commission, said that Mr Shkreli had committed "nearly every aspect of hedge-fund investments and in connection with his stewardship of a public company."
