The strange story of Sergey Cherkasov, the spy who went to Trinity

Russian spy Sergey Cherkasov spent four years deep undercover as a politics student in Trinity College Dublin. His classmates knew him as Victor Muller Ferreira, a Brazilian national, eager to further his education and his prospects in Ireland. Five years on from his graduation, Cherkasov is in Brazil serving a 15 year prison sentence for several counts of fraud.

The Trinity graduate is facing charges in the US, for acting as an illegal agent of the Russian intelligence service; in other words – a spy. Irish Times public affairs editor Simon Carswell explains how Cherkasov was busy making connections but unusually careless about leaving an information trail. A carelessness that finally caught him in the end.
