As noted, these persons are put on the international wanted list by Interpol.

The prosecutor's office suggests that they use other names: Georgy Gorshkov - Egor Gordienko, Sergey Pavlov - Sergey Lyutenko, Sergey Fedotov - Denis Sergeev.

“The prosecutor’s office has taken measures to supplement and update the already issued European arrest warrants, as well as requests for an international wanted list for detention and subsequent extradition,” the statement said.

In addition, the investigation established that the substance used for the poisoning was the organophosphorus compound chlorpyrifos. 

At the end of January, Bulgaria brought charges against the Russians, who allegedly tried in 2015 to poison businessman Emilian Hristov Gebrev, his son and partner with an "unidentified organophosphorus substance."

The official representative of the Russian Foreign Ministry, Maria Zakharova, emphasized that in the case of criminal proceedings against foreigners, countries should interact through law enforcement agencies.

On April 28, 2015, businessman Gebrev, during a dinner with partners, felt unwell and was hospitalized.

His son also went to the hospital with similar symptoms.

The examination showed the presence in the salad, which the businessman ate, traces of chlorpyrifos, used for pest control.

Pesticides were also detected in samples of the detected chemicals in 2018 re-analysis.
