Germany Arrests Second Ukrainian Suspect in 2022 Nord Stream Pipeline Explosions

Croatian authorities detained a trained scuba diver identified as Vladimir Z. in Pula, accused of planting explosives on Russian gas pipelines to Germany

German federal prosecutors announced Wednesday that Croatian police arrested a Ukrainian national in the coastal city of Pula on a European arrest warrant. Vladimir Z., identified as a trained scuba diver, is accused of being part of a group that planted explosives on the Nord Stream 1 and Nord Stream 2 pipelines near the Danish island of Bornholm in September 2022. The suspect faces charges of jointly causing explosions, anti-constitutional sabotage, and destruction of infrastructure. He will be extradited to Germany to face trial. This marks the second arrest in the case. In July, German prosecutors charged former Ukrainian army officer Serhii K., who was arrested in Italy in August 2025 and extradited to Germany in November. Prosecutors allege Serhii K. orchestrated the operation while acting on behalf of Ukrainian state entities, a claim Ukrainian authorities say they lack sufficient information to address. The first suspect has denied involvement. The underwater explosions on September 26, 2022, severely damaged three of the four pipeline strings, halting Russian natural gas flows to Germany through the Baltic Sea. Prosecutors say the alleged aim was to permanently cut off gas deliveries and prevent Russia from using energy revenues to finance its military campaign in Ukraine. Germany is the only country still investigating the blasts after Denmark and Sweden closed their probes in early 2024, citing jurisdictional limitations.

How could this affect you

Traced by who's actually in the path of this — not everyone is.

Likely

If you're tracking European energy security

The arrests suggest Germany is advancing its investigation into infrastructure sabotage that severed a major Russian gas route to Europe, potentially shaping future pipeline security policy and bilateral energy relations

Likely

If you follow Ukraine-Russia war dynamics

German prosecutors allege the operation was designed to cut Russian energy revenues funding the war effort, raising questions about covert actions attributed to Ukrainian nationals and potential diplomatic friction between Kyiv and Berlin

Chanakya's Move

Whose move this was, what they're betting on, what could counter it.

This is Germany asserting jurisdiction over an act of sabotage that other European states declined to pursue. By charging suspects allegedly acting on behalf of Ukrainian state entities, Berlin walks a tightrope: it maintains legal credibility by investigating attacks on its own infrastructure, while risking tension with Kyiv at a moment when Western unity on Ukraine remains critical. The counter-move space is narrow. Poland already blocked one extradition, signaling regional divergence on how aggressively to pursue this case. If Berlin secures convictions, it establishes precedent that even wartime sabotage against Russian assets has legal consequences when European infrastructure is involved. If the trials stall or evidence proves inconclusive, the investigation itself becomes the message: infrastructure attacks carry investigative costs, regardless of the target.
