Bellingcat investigation agency and its international partners conducted four months-long research, which shed some more light on the Salisbury incident. The investigation found out the real identity of the third suspect in the nerve agent attack on ex-GRU agent Sergey Skripal and his daughter Yulia.
'Following a four-month joint investigation with our investigative partners The Insider (Russia) and Respekt (Czechia), Bellingcat can now reveal the true identity and background of this GRU officer, who operated internationally under the cover persona of Sergey Vyachaeslavovich Fedotov. In fact, this person is Denis Vyacheslavovich Sergeev, a high-ranking GRU officer and a graduate of Russia’s Military Diplomatic Academy', reads the story on the investigation agency's web site.
Bellingcat added that 'in the last two months, Russian authorities have taken the unusual measure of erasing any public records of the existence of Denis Sergeev, as well as of Anatoly Chepiga and Alexander Mishkin, the main two suspects in the Skripal poisoning. These unprecedented actions cannot plausibly be taken without the direct involvement of the Russian state, and add further credibility to the UK government’s assertion that the Skripal poisoning operation, and the subsequent cover-up, were coordinated at a state level'.
