Pharma's bad boy: Livestreaming, rap-loving CEO Martin Shkreli faces fraud charges

He's the enfant terrible of pharmaceuticals. He's a millionaire music fan who riled rap aficionados by buying the only known copy of an album by the Wu-Tang Clan. He's an unabashed self-promoter who livestreams his daily life and boasts he's "the world's most eligible bachelor."

Now, prosecutors say Martin Shkreli is a fraudster whose deceit has spanned hedge funds and drug companies.

And he's only 32.

Shkreli pleaded not guilty Thursday.

The criminal charges are unrelated to the events that made him a flashpoint this year. That's when his Turing Pharmaceuticals raised the price of the only approved drug for a rare parasitic disease from $13.50 to $750 per pill.

The charges concern a drug company and hedge funds he previously ran.
