A Russian newspaper has claimed that the banker shot in London on Tuesday believed he would be killed if he returned to Russia.
Kommersant reports that German Gorbuntsov was involved in the investigation into a 2009 assassination attempt on another banker, Alexander Antonov.
Mr Gorbuntsov's lawyer, Vadim Vedenin, told Kommersant that his client gave a testimony to Russian police implicating two of his former business contacts in the Antonov case.
Gorbuntsov has also been named in anti-corruption investigations in Moldova. However, Gorbuntsov's Moldovan lawyer told Kommersant he didn't think the London shooting could be linked to Moldova since Gorbuntsov told him "several times" that he believed he would be killed if he returned to Russia.
