In September 2018, in collaboration with the Bellingcat network and the BBC's "Newsnight" television program, "The Insider" conducted an investigation, publishing copies of official documents of the Federal Migration Service of Russia claiming to issue a passport in the name of Alexander Petrov, one of individuals accused of poisoning Sergei and Yulia Skripal in the United Kingdom, indicating his connection with the Russian intelligence agencies. The documents were provided by a source from the Russian police. Roman Dobrokhotov himself admitted that he did not know how the personal data of "Boshirov" and "Petrov" were obtained, stating that he himself "did not violate any laws", and that "The Insider" received information from Bellingcat. "The Insider" also discovered that the third participant in the poisoning of Skripal was associated with the poisoning of Bulgarian businessman Emilian Gebrev in 2015.
