Sweden is reeling from the unexpected death of a high-ranking diplomat who was recently questioned by Säpo (Swedish Security Service) on suspicion of espionage. The diplomat, who was arrested last Sunday and released on Wednesday, was found dead in his Stockholm residence on Friday.
The case has sent shockwaves through Sweden’s foreign ministry, where Foreign Minister Maria Malmer Stenergard expressed deep sorrow over the incident. “It has been a difficult day. My thoughts are with his family and colleagues,” she said, adding she could not comment further due to the ongoing investigation.

Diplomat Under Scrutiny
Although the man’s identity remains officially undisclosed, media reports confirm he was in his 50s and had served as an ambassador in various postings outside Europe. According to BBC News, his flat door had been forced open during his arrest, and he had later filed a formal complaint alleging excessive force by Säpo agents.
His attorney, Anton Strand, stated: “I have ensured his formal report about abuse during the arrest has arrived to the special investigations unit. An investigation has started regarding this.” However, Säpo insists the arrest was conducted peacefully.
Possible National Security Link
Unconfirmed reports by Sweden’s public broadcaster SVT suggest Säpo may have been investigating a potential connection between the diplomat’s case and the recent, abrupt resignation of Sweden’s newly appointed National Security Adviser Tobias Thyberg.
Thyberg stepped down mere hours after taking on the role, following the anonymous circulation of sensitive images of him on the dating app Grindr. While authorities have not confirmed a direct link, the timing has fueled speculation.

Tributes from Colleagues

Former Swedish foreign minister Carl Bildt described the deceased diplomat as “extremely gifted and competent,” highlighting his decades-long contribution to Sweden’s diplomatic service.
Prosecutor Per Lindqvist confirmed that the preliminary espionage investigation remains open. “The death is very regrettable, and the case is not yet closed,” he told Swedish television.
What’s Next for the Investigation?
Police have stated that there were no suspicious circumstances surrounding the diplomat’s death. However, public and political pressure is mounting as Sweden grapples with the implications of this case for national security and diplomatic integrity.
