Berezovsky, who was granted political asylum in the U.K. in 2003 after fleeing prosecution in his home country on fraud and money laundering charges, told The Guardian that he has bankrolled Kremlin insiders conspiring to overthrow President Vladimir Putin.
Scotland Yard did not specify whether they began studying the statement at Russia's request.
On Friday, Russian prosecutors said they would take legal action against Berezovsky and renewed their calls for his extradition.
Berezovsky himself said that he never violated the law and he is not concerned by Russia's intentions to press new charges against him.
"Everything that I do is absolutely legal," he said to journalists commenting on his interview with The Guardian. "I am not worried that Russia will form some platform to bring new charges against me."
Berezovsky is already facing sedition charges, brought against him in February 2006 after he made similar comments in an interview with a major French news agency.
"Any violent actions on the part of the opposition in Russia will be justified today. Including a coup. This is precisely what I am working on now," he told Agence France-Presse.
