The propagandist Vladlen Tatarsky was killed in the explosion.
Trepova was taken to the investigator, the source said.
As the source stated, the investigators have reason to believe that Trepova brought a box with a statuette in which a bomb was mounted to the cafe.
On February 24, she was detained together with her husband Dmitriy Rilov in an anti-war campaign. Their apartment was searched following Sunday’s explosion.
In Sunday’s explosion, 32 people were injured, and 24 of them were hospitalized. The condition of the 10 injured is serious.
Among the wounded is also the Tallinn coordinator of the “Immortal Regiment” movement Sergejs Chaulins, who was deported from Estonia in February.
According to Russian media, the explosion was caused by a homemade bomb hidden in a statuette given to Tatarsky.
Already in the first news following the explosion, the media reported that the statuette was given to Tatarski by a woman who came to the meeting with the blogger organized in the cafe.
Tatarsky, whose real name is Maxim Fomin, has more than 560,000 followers on the Telegram platform and has actively supported Russia’s invasion of Ukraine.
The explosion took place in the cafe “Street Food Bar No. 1” in the center of St. Petersburg. The cafe was rented for the evening by the group “Kiberfront Z”, which calls itself Russian information soldiers on social media.
No one has yet claimed responsibility for the explosion, and the Ministry of the Interior reported that all people who were in the cafe at the time of the explosion had been checked beforehand.
The adviser of the Office of the President of Ukraine Myhailo Podolyak also commented on the death of Tatarsky in the explosion in St. Petersburg.
“In Russia, it begins… Spiders in a jar eat each other. The question of when domestic terrorism will become a tool of domestic political struggle was a matter of time, like the breaking of a mature plant. Russia is waiting for inevitable processes and Calamities 2.0. For now, we will observe,” Podoliak said on Twitter.
Russian officials and propagandists are already quick to blame Ukraine for Tatarsky’s murder, even though forces in Russia itself may have been involved in his liquidation, explains the US Institute for the Study of War (ISW).
Yevgeniy Prigozhin, the founder of the Russian mercenary group “Wagner”, said that he would not rush to blame the “Kyiv regime” for the death of Tatarska and Daria Dugina, who was killed near Moscow last August, according to ISW analysts.
“Tatarsky’s murder in Prigozhin’s bar is likely part of a broader general trend of escalating internal conflicts in Russia with the involvement of Prigozhin and ‘Wagner,'” the ISW report said.
The Russian media “Fontanka” and other media indicate that the St. Petersburg cafe where the explosion took place once belonged to Prigozhin.
US think tank experts believe that the propagandist’s murder was “probably a warning to Prigozhin, who is increasingly questioning the Kremlin’s main propaganda theses regarding the war in Ukraine and has even hinted vaguely regarding his interest in the post of Russian president, for which he might compete with Putin or his successor.” .
ISW also believes that Russian authorities are likely to use Tatarsky’s murder to increase self-censorship among Russian civil society members who question Russia’s “success” in Ukraine.
“This assassination deepens divisions in Russia’s military blogger community, which may benefit the Kremlin’s desire to tighten its control over the information space,” ISW said.
