Moscow (CNN) A woman who claimed to have insider knowledge of Moscow's attempts to meddle in the US elections has been detained in Russia, state media reported.

Anastasia Vashukevich, who goes by Nastya Rybka on social media, was deported from Thailand on Thursday after pleading guilty to charges including soliciting prostitution, a Thai immigration official said.

Upon arriving in Moscow's Sheremetyevo Airport, Vashukevich was detained on suspicion of enticement into prostitution, state media RIA-Novosti reported.

Earlier Thursday, Vashukevich told CNN via text message that she was detained by a group of people "in civilian clothes" who did not introduce themselves or say why she was detained.

"They speak very rudely!" the text message said. "They say we must go with them for a couple of days somewhere!"
