The man who sparked outrage last year by hiking the price of a life-saving drug may have met his match in some Australian schoolboys.
US executive Martin Shkreli became a symbol of greed when he raised the price of a tablet of Daraprim from $13.50 (£11) to $750.
Now, Sydney school students have recreated the drug's key ingredient for just $20.
Daraprim is an anti-parasitic drug used by malaria and Aids patients.
