The country’s interior ministry added Daria Trepova to a wanted list following the explosion, and her arrest was announced on Telegram by the Investigative Committee of Russia shortly after that.
State media outlet TASS reported that “preliminarily, it was Trepova who handed Tatarsky a figurine with explosives” at the cafe.
Russian media had reported suggestions that Tatarsky may have been killed by a device hidden in a statue presented to him by a woman. CNN is not able to independently verify the claims.
Trepova’s husband, Dmitry Rylov, has told an independent Russian publication that he is convinced she was set up.
Trepova was arrested in the early days of the conflict for demonstrating against it, TASS reported.
“Trepova participated in an unsanctioned rally on the day the special military operation began in Ukraine and was subjected to administrative arrest,” the article read, adding that court records confirmed that Trepova was arrested on March 9, 2022, and sentenced to 10 days in prison.
According to the TASS article, law enforcement officers conducted a search at Trepovas’ residence in St Petersburg on Sunday night, where her sister and mother were also questioned.
Trepova’s husband, Rylov, was a member of the Libertarian Party of Russia, the article said. Trepova, however, was not associated with the small political party.
The Libertarian Party said in a statement ON Monday that Trepova, “has never been a member of our party”
“According to our records, she has never been a supporter … either,” it said.
Husband says Trepova was ‘set up’
Russia’s National Anti Terrorism Committee (NAC) meanwhile claimed Monday that the explosion involved agents of the Ukrainian special services and associates of the jailed opposition leader Alexei Navalny, allegations that were immediately treated with scepticism.
Ivan Zhdanov, a long-time associate of Navalny, said the accusation was an attempt to prolong Navalny’s jail term.
“This is a rather idiotic situation. To refute the fact that we did it is idiocy. Obviously, we are not involved in this,” he said.
Kremlin spokesperson Dmitry Peskov repeated the claim during a news briefing that Ukraine may be behind the murder of Tatarsky, describing his killing as a “terrorist attack”.

US and Ukrainian officials have in the past warned that Russia has planned so-called “false flag” attacks inside Russian territory as a pretext for military escalation, including Russian claims ahead of last year’s full-scale invasion that Ukraine was sending “saboteurs” over the Russian border.
An independent Russian publication, The Insider, said it interviewed Trepova’s husband who believed his wife was framed.
“She was really just set up and used,” Rylov was quoted as saying.
“Over the last day I contacted her, but I lost contact about 4-5 hours ago.”
“All I knew was that Daria needed, either for some task, or for some reason, to give some gift, I didn’t even know what,” he said, referring to the event at which the explosion took place.
“There is one very important point that she told me several times: she was sure that this thing would allow access to a person. That is, it was not something that should have exploded,” he said.
“Dasha [Daria], in principle, is not the kind of person who could kill anyone.”
Russian state media Ria Novosti quoted one witness of Sunday’s blast as saying: “This woman sat at our table”.
“I saw her from the back as she was turned away,” they said.
“When she gifted him the figurine, she went to sit in a different place by the window and forgot her phone at our table.”

The witness added: “The host at the stage took the figurine from the box and showcased it, Vladlen held it for a bit.
“They put it back and shortly after the explosion happened … I was running and my ears were blocked. There were many people with blood on them,” they said.
The independent Telegram channel Astra Press quoted a witness as saying: “Everyone rushed to the exit when explosion happened.
“I myself saw the girl only until the moment of the explosion, when she gave a gift. She looked like an ordinary person,” the quote said.
