"If someone in front of you said that he receives money or work from Ukrainian sources, with the highest probability this someone took the path of betrayal. And he has already committed a criminal offense. He is an enemy and it is necessary to inform the special services or law enforcement agencies about him, "RIA Novosti quoted Medvedev's assistant Oleg Osipov in response to a request to comment on the explosion in St. Petersburg, in which military officer Vladlen Tatarsky died.

Earlier, the press secretary of the Russian leader, Dmitry Peskov, said that the Kiev regime supports terror and may be behind the murder of military leader Vladlen Tatarsky, like many others since 2014.

According to him, therefore, a special military operation is being carried out.

On April 3, it became known that Daria Trepova, suspected of involvement in the murder of Tatarsky, was detained in St. Petersburg. FAN, citing the Investigative Committee of Russia, reported that employees will establish the motives of the girl. To do this, the necessary investigative actions will be carried out.

The Ministry of Internal Affairs of Russia said that Trepova was detained in a rented apartment.
