A San Francisco hedge fund Monday accused Theranos Inc. and founder Elizabeth Holmes of lying to attract $100 million in investment in a lawsuit filed in Delaware. Partner Fund Management LP sent a letter to investors, accusing Theranos of “a series of lies, material misstatements, and omissions,” the Wall Street Journal reported. The letter said the company “engaged in securities fraud and other violations by fraudulently inducing PFM to invest and maintain its investment in the company.”
