Martin Shkreli blames ‘unjust’ arrest on drug price hikes

Martin Shkreli has been charged for engaging in what US prosecutors said was a Ponzi-like scheme at his former hedge fund MSMB Capital Management and Retrophin, a firm he headed before he took the helm of Turing Pharmaceuticals.
Earlier this year, after buying a 60-year-old drug called Daraprim, Turing raised the price overnight to $750 a tablet from $13.50.
