Both persons are suspected on probable cause, the stronger level of suspicion, of gross unauthorized handling of secret information.
"This means that the prosecutor has some kind of concrete evidence, there is something to take note of," says Johan Granlund.
The suspected crime can result in up to four years in prison. According to Johan Granlund, it is closely related to espionage crimes.
"The only difference is that if a person is convicted of espionage, they must have had the intention of acting on behalf of a foreign power. But in cases like this, it is enough to have handled security-sensitive documents incorrectly without the intention of acting on behalf of a foreign power," says Johan Granlund.
No later than 12 noon on Friday, the prosecutor must decide whether the suspects should be requested to be detained or released.
"We don't know how this will turn out if the prosecutor will go in with a request for detention or how the district court will act in that case," says Johan Granlund.
The arrested man denies any wrongdoing. The woman's defense attorney declined to comment on the case.
