Identity revealed of accused Russian spy posing as Brazilian researcher in Norway

A prosecutor with Norway's domestic security agency on Friday gave a Russian name for the man who entered the country as a Brazilian but is suspected of spying state secrets for Russia.

Thomas Blom of Norway's Security Service said the man's name was Mikhail Mikushin, adding authorities were "not positively sure of his identity, but we are quite certain that he is not Brazilian."

The man was detained Monday in the Arctic city of Tromsoe, where he worked at the Arctic University of Norway. Norwegian media have said he called himself Jose Assis Giammaria. Norwegian authorities said he was 44, born in Russia in 1978.
