London, Aug 16 (ANI): Business magnate George Soros has revealed that he spent around 10.6 million dollars buying over 341,000 shares of Facebook in the second quarter.

The new investment by the Hungarian-American investor and philanthropist, which was revealed in a regulatory filing by Soros Fund Management for his holdings at the end of June, is contrary to moves of other investors who have been rapidly “defriending” Facebook ever since its IPO in May.
