The billionaire family that controls OxyContin maker Purdue Pharma, already facing mounting legal and financial pressure, has been tossed out of a large hedge fund for its alleged role in fuelling the opioid crisis.

Investment entities of the Sackler family were told late last year by Hildene Capital Management that it was no longer comfortable managing their money. Hildene said last week that someone known by members of the firm had suffered an opioid tragedy.
