Mikhail Khodorkovsky
He was arrested on 25 October 2003. The government under Vladimir Putin then froze shares of Yukos shortly thereafter on tax charges. The state took further actions against Yukos, leading to a collapse of the company's share price. This destroyed most of Khodorkovsky's wealth. He was found guilty and sentenced to nine years in prison in May 2005. While still serving his sentence, Khodorkovsky and his business partner Platon Lebedev were further charged and found guilty of embezzlement and money laundering in December 2010, extending his prison sentence to 2014.
