Prosecutors say the man, identified only as ‘Sergej K’, has been in ‘continuous contact’ with Russian intelligence.

German authorities have arrested a Kazakh man in Berlin on suspicion of spying for Russia, according to the German Federal Prosecutor’s Office.

Identified only as Sergej K, the man had been “in continuous contact from Germany with a Russian intelligence service” since at least May last year, the office said in a statement on Wednesday, a day after the arrest.

Prosecutors said Sergej K provided his Russian handler with details about German military aid for Ukraine, including companies involved in developing drones and robotic systems. He also allegedly sent photos of NATO military convoys and public buildings in Berlin.

Other activities included offering to find other espionage agents in Germany, prosecutors added, but they did not make clear whether he had done so.

There was no immediate reaction from Kazakhstan or Russia.

Previous cases

The case is the latest in a string of Moscow-linked espionage and disinformation plots German authorities claim to have discovered since Russia’s full-scale invasion of Ukraine in 2022.

Two German-Russian dual nationals were arrested in 2024 on suspicion of plotting sabotage attacks on United States military sites in Germany to undermine Western military support for Ukraine.

German police have also arrested various alleged “disposable” agents, known to carry out sabotage and espionage without any formal training for Russia in exchange for small payments.

Earlier this month, Berlin summoned the Russian ambassador to condemn what it called “direct threats” against “targets in Germany”.

Berlin’s Federal Foreign Office said at the time that the threats were intended to undermine Germany’s support for Ukraine. “Our response is clear: we will not be intimidated. Such threats and all forms of espionage in Germany are completely unacceptable,” the Foreign Office said.

Germany has also accused “state-sponsored” Russian hackers of carrying out an “intolerable” 2023 cyberattack on members of the Social Democratic Party, a charge that Russia’s embassy in Germany “categorically rejected”.

Meanwhile, Russia has essentially banned Germany’s international broadcaster Deutsche Welle on the grounds that it produces “hostile anti-Russian propaganda”.

Moscow has repeatedly denied any involvement in Germany-based espionage schemes.
