Russian mafia whistleblower, 44, found dead in UK

WEYBRIDGE, England/LONDON (Reuters) - A Russian businessman helping Swiss prosecutors uncover a powerful fraud syndicate has died in unexplained circumstances near his mansion in Britain, in a chilling twist to a Russian mafia scandal that has strained Moscow's ties with the West.

Alexander Perepilichny, 44, sought refuge in Britain three years ago and had been helping a Swiss investigation into a Russian money-laundering scheme by providing evidence against corrupt officials, his colleagues and media reports said.

He has also provided evidence against those linked to the 2009 death of anti-corruption lawyer Sergei Magnitsky, a case that caused an international outcry and prompted the United States to push for a bill cracking down on Russian corruption.

Perepilichny, a Russian citizen, collapsed and died not far from his home on an upmarket, heavily protected estate in the county of Surrey, south of London, on November 10.
