Martin Shkreli branded an 'attention seeker' as Sydney student hits back

'Pharma bro' who hiked the price of Daraprim by 5,000% goes on defensive after year 11 students make same life-saving drug in their school laboratory

One of the students who made the life-saving medicine Daraprim in a school laboratory has accused Martin Shkreli of being "an attention-seeking businessman" who forgets there are "people's lives and livelihoods at stake" in the row over predatory drug pricing.

Former hedge fund manager Shkreli last year bought Turing Pharmaceuticals and almost immediately increased the price of the drug - which has been off-patent since the 1970s - from US$13.50 to US$750 a tablet.
