A Second Person Has Been Arrested for Blowing Up the Nord Stream Gas Pipelines

Croatian police arrested a second Ukrainian man on August 19, 2026, in the coastal city of Pula. They acted on a European arrest warrant, which is a request one EU country can make to another to arrest and hand over a suspect. Germany issued the warrant. The suspect, identified as Vladimir Z, is expected to be sent to Germany, where prosecutors say he helped blow up the Nord Stream 1 and Nord Stream 2 gas pipelines in September 2022 (Al Jazeera).

Germany's top federal prosecutor described Vladimir Z as a trained scuba diver who worked in a group led by a former Ukrainian army officer named Serhii K. Serhii K was charged in July with planning the underwater blasts. According to prosecutors, the group planted explosives on the ocean floor near the Danish island of Bornholm and set them off on September 26, 2022. The explosions badly damaged both pipeline systems (Al Jazeera) (Generalbundesanwalt).

Serhii K was the first suspect charged in the case. He was arrested in Italy in August 2025 and moved to Germany in November of that year. He has denied any involvement in the explosions. The federal prosecutor's office first announced his arrest in August 2025, then filed formal charges — the official step that starts a criminal trial — on July 2, 2026 (Al Jazeera) (Generalbundesanwalt, August 2025) (Generalbundesanwalt, July 2026).

German prosecutors have said the goal of the operation was to permanently stop gas from flowing through the pipelines and to prevent Russia from using natural gas sales to fund its war in Ukraine. Serhii K was charged with carrying out the sabotage on behalf of Ukrainian state entities, meaning groups connected to the Ukrainian government (Al Jazeera).

German courts said they have the right to try the case because the pipelines end in the German state of Mecklenburg-Vorpommern. Prosecutors argued that the destruction of the pipelines affected Germany's energy security and internal safety, which gave German authorities the legal basis to pursue the case (Al Jazeera).

The German government welcomed the arrest of Vladimir Z. Justice ministry spokesman Nicholas Limmer said the federal prosecutor's office is making progress in the investigations (Al Jazeera) (Reuters).

The Nord Stream pipelines were built to carry Russian natural gas directly to Germany under the Baltic Sea. Before the explosions, they were a key part of Europe's energy infrastructure — the network of pipelines and facilities that heat homes and power factories across the continent. The blasts happened seven months into Russia's full-scale invasion of Ukraine, when European governments were already trying to cut their reliance on Russian energy.

The broader context here matters for several reasons. The prosecutors' explanation of the motive ties the sabotage directly to the economic side of the Ukraine war. They say the operation aimed to cut off a source of money for Moscow. If that argument holds up in court, the Nord Stream attack would be treated as state-directed economic warfare, not just sabotage by individuals acting on their own. The charge that Serhii K acted on behalf of Ukrainian state entities turns the case from an ordinary criminal trial into a politically sensitive inquiry that could implicate a government.

The arrest of a second suspect also suggests the German investigation is growing, not winding down. With one accused operative already charged and a second awaiting transfer to Germany, prosecutors seem to be building a case that goes beyond a single person. The fact that European arrest warrants were used in two different EU countries — first Italy, then Croatia — shows the EU's system for cross-border cooperation working quickly, even in a case with major political stakes.

Germany's claim to jurisdiction is worth noting as well. The pipelines end in German territory, and prosecutors say the damage hurt Germany's energy security. That is a broad legal claim for an act that physically took place in international waters near Bornholm. It reflects an approach that treats the destruction of infrastructure as a domestic security issue when the effects are felt on German soil, no matter where the explosives were planted or who planted them.

What happens next will depend on what Vladimir Z says once he is in German custody, whether he confirms or pushes back against the prosecution's story, and whether more suspects are identified. Serhii K's denial of involvement raises the possibility of conflicting accounts during a trial that is likely to draw sustained international attention.
