Russia’s FSB security service announced U.S. citizen Eugene Spector was sentenced to 15 years in prison for stealing biotechnology secrets.

Russian state news agencies reported on Tuesday that Spector, who was born in Russia and then moved to the US, had been handed a 13-year jail sentence for spying. This was added to an existing bribery sentence and converted into a new 15-year jail term in a maximum security penal colony.

Eugene Spector, a US citizen jailed for a total of 15 years this week after a Moscow court convicted him of espionage, was found guilty of passing biotechnology secrets to the United States, Russia's FSB security service said on Friday.
