Sergei Leonidovich Magnitsky (Russian: Серге́й Леони́дович Магни́тский; 8 April 1972 – 16 November 2009) was a Ukrainian-born Russian tax advisor. His arrest in 2008 and subsequent death after eleven months in police custody generated international media attention and triggered both official and unofficial inquiries into allegations of fraud, theft and human rights violations in Russia. In early January 2013, the Financial Times wrote that "the Magnitsky case is egregious, well documented and encapsulates the darker side of Putinism".
