Fritiof Enbom

[1][2] Born in Luleå, Enbom was a former worker at the Swedish State Railways in Boden, and later the local editor for the Communist newspaper Norrskensflamman.

[3] The family told the Swedish Security Service after the Christmas holidays of 1951, and Enbom was arrested on 16 February 1952.

[1] Enbom had provided a large variety of intelligence, most of it from public sources, but also secrets about armaments in Boden Fortress and nearby fortifications.

[4] In hindsight it has been proven that most of the information that Enbom gave to the Soviet Union was public and could be easily found by anyone interested.

[4] Lund University professor Wilhelm Agrell, on the other hand, has concluded that Enbom provided KGB agent Vladimir Petrov with a lot of secret information from Sweden about its defence.
