Igor Sutyagin, a Russian scientist jailed for spying for the U.S., arrived in the Austrian capital Vienna on Thursday, his lawyer said.
Anna Stavitskaya earlier said Sutyagin could be swapped for one of the ten suspected Russian spies detained in the U.S. in late June.
"Igor's father received a phone call at approximately 16:30 Moscow time, and he was told that he [Sutyagin] was seen getting off a plane in Vienna," she said.
