The statement gave no further information about the suspect’s identity, but said that the suspect had been charged with “aggravated espionage”. It added that the arrest was connected with “a similar case” that led to an arrest of an intelligence officer in September, also connected to espionage. The “similar case” mentioned in the statement refers to the arrest of Peyman Kia, a senior civil servant and former intelligence officer, who was arrested in a pre-dawn raid on September 20 of this year.

Kia is believed to have been an officer in SÄPO, as well as in the Office for Special Information Gathering (KSI) of the Swedish Military Intelligence and Security Service (MUST). The KSI is reportedly among the most sensitive branches of the MUST. According to a number of reports in the Swedish media, Kia is of Iranian origin and is accused of having provided Iran with intelligence information. Specifically, he is “suspected of having committed serious crimes against the security of the Swedish state during the period 2011–2015”, according to reports.

The most recent arrest is reportedly directly connected with that of Kia. Swedish counterintelligence officials have described these cases as “complex”, adding that they have been “working on them for a long time”. If the charges hold in court, it will make this the first espionage affair affecting an employee of SÄPO since 1979.
