Brazil judges block international requests to extradite alleged Russian spy
July 31, 2023 1 Comment
THE BRAZILIAN GOVERNMENT IS blocking requests from the United States and Russia to extradite an alleged Russian deep-cover spy, whose forged Brazilian identity papers were discovered by Dutch counterintelligence. Sergey Cherkasov was expelled by authorities in the Netherlands in June 2022, after he attempted to enter the country using a Brazilian-issued passport under the name of Victor Muller Ferreira.
Within a few days of his expulsion, Dutch and American counterintelligence had outed Cherkasov as an intelligence officer of the Main Directorate of the Russian Armed Forces’ General Staff, which is commonly known as GRU. Cherkasov is alleged to have built his forged identity over several years, while operating in Brazil and the United States. Upon returning to Brazil, Cherkasov was sentenced to 15 years in prison for using forged Brazilian identity documents.
Last week, Cherkasov’s sentence was reduced to 5 years, after a court in Brazil dropped some of the initial charges that had been filed against him by the Brazilian government prosecutor’s office. Cherkasov’s lawyers are now arguing that their client does not pose a flight risk and should therefore be allowed to serve the remainder of his sentence outside of prison, wearing an electronic tagging device.
These recent developments are of concern to authorities in the United States. The latter have filed an extradition request for Cherkasov, claiming that he spent several years as a graduate student in an American university while using his forged Brazilian identity papers. During that time, Cherkasov is alleged to have repeatedly communicated with his Russian intelligence handlers, supplying them with information about American politics and policy.
However, the Ministry of Justice and Public Security of Brazil said on Friday that Washington’s extradition request had been denied and that Cherkasov would remain in Brazil. The apparent reason for the denial is that Brazil’s Supreme Federal Court had already approved a similar extradition request for Cherkasov, which was filed in April by the Russian government. Moscow claims that Cherkasov is wanted in Russia for narcotics trafficking. The Russians also deny that the alleged spy worked for the GRU or any other government agency.
Yet, despite claims to the contrary, the Brazilian government appears to be essentially stalling on Moscow’s extradition request. On Friday, Flávio Dino, who serves as Minister of Justice under the administration of President Inácio Lula, stated that Cherkasov would continue to serve his prison sentence in Brazil until further notice. In the United States, CBS News reported that Cherkasov’s extradition to Russia would take place “only […] after the final judgment of all of his cases here in Brazil” has been issued, according to the accused spy’s lawyers.

A RUSSIAN INTELLIGENCE OPERATIVE, who lived in Maryland using forged Brazilian identity documents, has been charged with espionage and other crimes by the United States Department of Justice.

A convoy of trucks carrying nuclear fuel to one of Brazil’s nuclear plants was attacked by a heavily armed gang on Tuesday, according to police reports. The convoy was carrying uranium fuel from Resende, an industrial city in the municipality of Rio de Janeiro in southeastern Brazil. Its destination was the Angra Nuclear Power Plant in the coastal city of Angra dos Reis, which is located 100 miles south of Resende. Angra is Brazil’s sole nuclear power plant. It consists of two pressurized water reactors, Angra I and Angra II. It is owned by Eletrobras, Brazil’s state-owned power utility firm, which is also the world’s tenth largest electric utilities company.
A retired general, who rose through the military’s ranks during Brazil’s 20-year dictatorship, will head the country’s intelligence agency as one of several military men in the new cabinet of President Jair Bolsonaro. Augusto Heleno, 71, was sworn in on Tuesday as head of the Institutional Security Cabinet (GSI), which advises the president on security policy and oversees Brazil’s intelligence and counterterrorism services.

Brazilian police have announced the arrest of Assad Ahmad Barakat, a Lebanese national who is believed to be one of the most prolific international financiers for the Shiite group Hezbollah. Barakat was born in Lebanon but fled to Paraguay in the mid-1980s in the midst of Lebanon’s brutal civil war. He began an import-export business and eventually acquired Paraguayan citizenship. He gradually built a small business empire in Paraguay, which included engineering and construction, as well as transportation firms. Throughout that time, however, Barakat maintained strong connections with Hezbollah, the paramilitary group that has a strong following among Lebanon’s large Shiite Muslim community.
The director of Argentina’s spy agency has been accused by security officials in Brazil of being implicated in a multi-million dollar money-laundering scandal that involves dozens of senior officials across Latin America. The allegations were made in the context of the so-called “operation car wash”, known in Portuguese as Operação Lava Jato. The term refers to a money-laundering probe that began in 2014, following allegations of illegal financial practices by a number of private import-export companies in Brazil. Soon, however, Lava Jato led to the exposure of large-scale corruption, nepotism and bribing practices at the core of Brazil’s state-owned oil company Petrobras. Today, four years later, the constantly expanding investigation has implicated nearly 200 people —many of them well-known politicians— in numerous Latin American countries, including Mexico, Peru and Venezuela.

Portuguese weekly newspaper Sol said on Saturday that Danilov used a Brazilian passport and supplied authorities with documentation showing his father was a Portuguese national. This allowed Danilov to eventually obtain Portuguese citizenship. Although Danilova did not apply for Portuguese citizenship, she was granted permanent residency by the European Union country. These credentials enabled the spies to move freely in the European Union’s 27 member-states without restriction.
In 2022 the Brazilian Federal Police, with the assistance of United States intelligence agencies, launched a lengthy investigation into the activities of several Russian spies who operated in Brazil in recent years. The spies appear to have used concocted Brazilian identities in order to operate around the world undetected. The investigation eventually incorporated counterintelligence services from as many as eight countries, including Portugal, according to Sol.
So far the Portuguese investigation has revealed that the Danilovs conducted a variety of espionage operations in the coastal city of Porto, which is Portugal’s second-largest urban center following the capital Lisbon. Using Porto as an operational base, the couple traveled extensively around the world using their Brazilian and Portuguese passports. Each time they were able to return to their home in Porto “without encountering any issues”, Sol reports. The two spies have vanished and their current whereabouts are unknown.
