Zuckerberg set up fraudulent scheme to 'weaponise' data, court case alleges

Facebook CEO exploited ability to access data from any user's friend network, US case claims

Mark Zuckerberg faces allegations that he developed a "malicious and fraudulent scheme" to exploit vast amounts of private data to earn Facebook billions and force rivals out of business.

A company suing Facebook in a California court claims the social network's chief executive "weaponised" the ability to access data from any user's network of friends - the feature at the heart of the Cambridge Analytica scandal.
