British police probing the death of former tycoon Boris Berezovsky are now also investigating an alleged plot to kill former Bank of Moscow president Andrei Borodin, the Daily Mirror reported on Monday.
A would-be hitman said he was offered £660,000 to kill the 45-year-old billionaire, who fled to the UK in 2011, the newspaper said.
The newspaper did not disclose any further details.
Borodin was granted asylum in the U.K. in February 2013 after claiming he was persecuted by Vladimir Putin's allies.
In March, Russia asked to extradite Borodin, who has four criminal charges outstanding against him, including an accusation of embezzling billions of rubles during his time leading Russia's fifth-largest bank.
He denied the charges and said they were politically motivated.
In December, Thames Valley Police said it had "received a report about a perceived threat to a 45-year-old man," according to the Daily Mirror.
Borodin's £140 million home is located in the town of Henley-on-Thames in Oxfordshire, and is approximately 22.5 kilometers from Berezovsky's Ascot mansion, where the 67-year-old was found dead last month.
