German authorities searched the home of a man in connection with the massived data breach that affected politicians and other public figures, media reports said on Monday.
The 19-year-old’s flat in the south-western city of Heilbronn was searched on Sunday, broadcasters ARD and rbb-Inforadio
reported citing security sources.
Electronic devices were seized from the man, who is being treated as a witness in the investigation.
The almost 1,000 cases of leaked information saw stolen personal data published by an anonymous Twitter account.
The affair has unleashed debate and fierce criticism concerning the reaction of security authorities.
The Federal Office for Information Security (BSI) was aware of leaks in early December but only realized the full extent of the breach early Friday.
German Chancellor Angela Merkel and President Frank-Walter Steinmeier were targeted, while celebrities and journalists were also among the victims.
Interior Minister Horst Seehofer, who is increasingly under pressure to provide answers, is due to meet with high-ranking police and cyber security officials later.
