The murder of a top Russian banker has stunned the country’s financial establishment and raised the spectre of renewed attacks on anti-corruption officials. Andrei Kozlov, was a first deputy chairman of the central bank. He had spearheaded a campaign to clean-up Russia’s murky banking system. The 41-year-old was shot outside a sports stadium in Moscow last night. Police say it appeared to be the work of contract killers. Attacks on leading financial figures were common in the 1990’s but they tailed off after 2000 when President Vladimir Putin came to power. Kozlov led a relentless campaign to close banks suspected of involvement in money laundering.
