Second Arrest in the Nord Stream Pipeline Bombing Case
Croatian authorities have arrested a Ukrainian man in the seaside town of Pula in connection with the September 2022 bombing of the Nord Stream gas pipelines, and Germany is seeking his extradition to face trial at the federal court in Karlsruhe (The Guardian; BBC).
The suspect is identified by German prosecutors as Vladimir Z and named in Polish court proceedings as Volodymyr Zhuravlev. He is a trained scuba diver whom the German Federal Public Prosecutor General (Generalbundesanwalt) alleges was directly involved in planting explosives on the Nord Stream 1 and Nord Stream 2 pipelines near the island of Bornholm (The Guardian; DW). The explosives detonated on 26 September 2022, causing severe damage to both pipelines, according to the Generalbundesanwalt's indictment press release of 2 July 2026 (Generalbundesanwalt). Three of the four Nord Stream pipelines, built to carry Russian fossil gas to Germany under the Baltic Sea, were damaged in the blasts, which occurred months after Russia's full-scale invasion of Ukraine (The Guardian).
The arrest in Croatia is the second detention of a suspect in the case. German authorities had previously published an official press release on 21 August 2025 announcing an arrest connected to the suspected sabotage (Generalbundesanwalt). That suspect, identified as Serhiy K, was arrested in Italy in August of the prior year and extradited to Germany in November after unsuccessful appeals in Italian courts (The Guardian). Both the newly arrested man and the suspect already in German custody are Ukrainian nationals (CBC; DW).
The German prosecutor's office alleges that Vladimir Z belonged to a group that included Serhiy K and that together they planted the explosives on the pipelines (The Guardian). German authorities state that the newly arrested suspect is strongly suspected of jointly causing the Nord Stream pipeline explosions (DW).
This is not the first time Vladimir Z has been detained in connection with the investigation. He was previously arrested by Poland, which released him after a Polish court ruled against executing a European arrest warrant issued by Germany (The Guardian). The European arrest warrant is an EU mechanism that allows one member state to request the arrest and transfer of a suspect from another member state, streamlining extradition within the bloc. The Polish court's reasoning was twofold: it argued that Germany had no jurisdiction in the Nord Stream case, and it further asserted that the destruction of Nord Stream could be seen as a justified action by Ukraine as part of a defensive war (The Guardian).
The broader context here matters for several reasons. The Nord Stream bombings have been the subject of multiple national investigations since September 2022, with Sweden and Denmark both conducting probes before closing them, and Germany pursuing its own parallel investigation that has now produced two arrests and a formal indictment. The case sits at the intersection of international criminal law, EU judicial cooperation mechanisms, and the politics of the Russia-Ukraine war. Germany's assertion of jurisdiction over sabotage of pipeline infrastructure that was, at the time of construction, a bilateral German-Russian energy project raises questions about which state's legal framework properly governs the destruction of cross-border energy assets during an active armed conflict. The Polish court's defensive-war rationale, if echoed by Croatian jurisprudence, would introduce into EU extradition proceedings a doctrinal claim that sabotage of energy infrastructure can constitute lawful belligerent conduct (that is, a legitimate military action during wartime), a position with implications well beyond this single case.
Berlin's extradition request will test whether the Polish precedent was an outlier or the first articulation of a judicial reasoning that could complicate Germany's efforts to bring both suspects to trial in Karlsruhe. With Serhiy K already in German custody following Italy's willingness to extradite, the Croatian proceedings will determine whether the two alleged perpetrators of the Nord Stream sabotage face trial together in a German federal court, or whether the case fractures along the jurisdictional and doctrinal fault lines that Poland's court identified.
