Paul Whelan was detained during a "spy operation" in Moscow in late December on suspicion of espionage, according to the Russian Federal Security Service (FSB). Whelan had allegedly gone to Moscow to attend a friend’s wedding.
"I'm aware that he has 4 citizenships," David Whelan said on Friday. "And I do not have any plans to visit Russia, nor does my family," he added.
US Ambassador to Russia Jon Huntsman visited Whelan and offered him assistance earlier this week, Andrea Kalan, the spokeswoman of the US embassy in Moscow told the RIA Novosti news agency.
Paul Whelan is currently employed as the director of global security with Michigan-based automotive components supplier BorgWarner. Whelan is also a former US marine. His service record, released by media, showed he had been convicted in 2008 on theft charges.
