A Belarusian model and self-styled sex instructor who last year claimed to have evidence of Russian interference in the 2016 U.S. presidential election said Saturday that she apologizes to a Russian tycoon for the claim and won't say more about the matter.

Anastasia Vashukevich made the statement in a Moscow court that was considering whether to keep her in jail as she faces charges of inducement to prostitution. The court extended her detention for three more days.

Vashukevich's statement appears to head off any chance of her speaking to U.S. investigators looking into possible collusion between Russia and President Donald Trump's campaign.

Vashukevich, who goes by the name Nastya Rybka on social media, was arrested in Thailand last February on prostitution charges. She and several others were arrested in connection with a sex training seminar they were holding in Thailand.

After her arrest she claimed she had audio tapes of Russian tycoon Oleg Deripaska, who is close to President Vladimir Putin, talking about interference in the U.S. election.

She had shot to world attention a few weeks earlier when a Russian opposition leader published an investigation based on her social media posts that suggested corrupt links between Deripaska and Deputy Prime Minister Sergei Prikhodko. The report featured video from Deripaska's yacht in 2016, when Vashukevich says she was having an affair with him.
