Arrest Details and Allegations

Norway’s domestic intelligence agency, PST, said Thursday night that the man was arrested in his garage at home on Wednesday on suspicion of having damaged national security with his intelligence-related activity.

The arrest warrant from the district court, says, among other things, that the police found records of the man’s assignment dialogue with a person who was apparently guiding his espionage activity, according to NRK.

The man has admitted to collecting and sharing information with Russian and Iranian authorities, the court order says, according to NRK.

It is too early to talk about the details of the man’s activity, PST spokesman Thomas Blom told a news conference Thursday night. PST has confirmed the man was employed as a security guard at the U.S. Embassy in Oslo. There are no other suspects in the case at this point.

The suspect’s attorney, John Christian Elden, told NRK that the man admits he worked for a foreign country but does not plead guilty of espionage.

“He is charged with having obtained information that could harm the security situation of third countries,” Elden said.
