Investigators say the murder of Spartak fan Egor Sviridov, which led to mass riots on Moscow’s central square in December 2010, was spurred by a "cultural misunderstanding" rather than ethnic hatred.
The deadly street fight involved five young men from Russia’s southern republics on one side and Sviridov, 28, and a few of his friends on the other.
