Russian investigators filed charges today against 26-year-old Daria Trepova for a “terror attack” in connection with the murder of military blogger Vladlen Tatarsky by a bomb explosion in St. Petersburg.

A staunch supporter of a military invasion of Ukraine, Tatarsky, whose real name is Maxim Fomin, was killed on Sunday in a cafe in St. Petersburg.

The Investigative Committee of Russia announced that Trepova had been charged with committing a “terrorist act by an organized group with the intentional infliction of death.” The charges carry up to 20 years in prison.

Her statement says that Trepova acted on instructions from people working on behalf of Ukraine.

The Russian Health Ministry said last Sunday’s explosion injured 40 people, of whom 25 have been hospitalized as of this morning.

Trepova was transferred from St. Petersburg to Moscow, where the investigators had to petition the Basmanny Court, located in the district of the same name, for her pre-trial detention.

Video footage of the event in a St. Petersburg cafe shows Tatarsky demonstrating the figurine to the public before it explodes.

Russia’s National Counter-Terrorism Committee today accused Ukrainian intelligence agencies of masterminding the assassination with the help of supporters of imprisoned Kremlin critic Alexei Navalny.

However, adviser to the President of Ukraine Volodymyr Zelensky, for his part, said that the attack was the result of internal conflicts in Russia.

Yesterday, Monday, Trepova’s husband told The Insider, an investigative journalism website, that he thought she had been set up.

Tatarsky himself fought in Ukraine on the positions of separatists, and also served time in Ukraine for bank robbery.

Last year, in a video filmed at a Kremlin ceremony marking Russia’s unilateral annexation of four Ukrainian regions, Tatarsky said Russia should “kill everyone” and “rob everyone” in Ukraine.
