PATTAYA, Thailand — Caught in a Thai police raid on her group’s seduction seminar, a Belarusian escort grabbed the world’s attention in February when she claimed to have audio recordings that might show a link between Russian officials and the election of President Trump, betting that it could turn into a get out of jail free card.

Six months later, her gamble appears to have badly backfired.

What began as a minor immigration charge has turned into a serious criminal case carrying the potential of 10 years of prison time in Thailand. And in a new interview with The New York Times, the escort, Anastasia Vashukevich, became coy about the content of her recordings — and said she now has no plan to make them public.

Ms. Vashukevich, who goes by the name Nastya Rybka online, remains in a Thai prison along with the Belarusian man she calls her seduction coach, Alexander Kirillov, and six of their Russian associates.

This past week, a judge set their trial for mid-January, after they all pleaded not guilty to charges of indecency, conspiracy and belonging to a secret society — an escalation of charges that they claim they are facing because of the intervention of a foreign power they angered.
