Looking more closely at “Rivera”, Grozev found that she travelled on several Russian passports with serial numbers in a range used by other known GRU operatives, including an officer who had been indicted for the alleged novichok poisoning of the Bulgarian arms dealer Emilian Gebrev, and another GRU officer reportedly involved in the attack on Sergei Skripal and his daughter in Salisbury in 2018.
He also discovered that on 15 September 2018, “Rivera” bought a ticket from Naples to Moscow. The previous day, Bellingcat and its Russian investigative partner, the Insider, published an article on the two Salisbury poisoners, who travelled under the cover identities Ruslan Boshirov and Alexander Petrov, noting irregularities in their passport data suggesting they had security services links.
It seems “Rivera” was withdrawn by her bosses, who feared that other operatives with similar passport numbers could be compromised. She does not appear to have left Russia again.Socialite who charmed Nato staff in Naples was Russian spy, say investigators | Espionage | The Guardian
