Arrest in Italy
German federal prosecutors announced that a Ukrainian man, named only as Serhii K, was arrested in Italy’s Rimini province on suspicion of being directly involved in the Nord Stream pipeline explosions. According to officials, he was part of a group that chartered a yacht from Rostock, Germany, before sailing into the Baltic Sea near Bornholm, Denmark, where the blasts occurred.
The arrest was carried out by Italy’s carabinieri military police in Misano Adriatico, a northern coastal resort. German prosecutors allege that the suspect played a key role in organizing and executing the sabotage operation. They stated that he will be extradited to Germany, where he is expected to appear before an investigating judge.

The Pipeline Explosions
The Nord Stream 1 and 2 pipelines, stretching 1,200km from Russia’s coast to Germany under the Baltic Sea, were vital conduits for natural gas before Russia’s full-scale invasion of Ukraine in 2022. While Nord Stream 2 was never operational, Nord Stream 1 had been a major supplier of energy to Europe until Moscow shut it down months before the blasts.
On 26 September 2022, multiple explosions ruptured three of the four pipelines near Bornholm. The attacks coincided with Europe’s scramble to secure alternative energy sources during an acute supply crisis triggered by the war.
Responsibility for the blasts has remained contested. Western officials suggested possible Russian involvement, while Moscow accused the US and UK of orchestrating the attack. Ukraine has denied playing any role.
Ongoing Investigations
German authorities last year issued a warrant for another Ukrainian diver, identified as Volodymyr Z, suspected of participation in the sabotage. Reports from 2023 indicated that Ukrainian-linked divers may have chartered a vessel to carry out the underwater operation, but evidence has remained circumstantial.
Prosecutors emphasized that despite the new arrest, there is no conclusive proof tying Ukraine, Russia, or any other state to the attack. The suspect faces charges of jointly causing an explosion and sabotage undermining Germany’s constitutional order.
The Nord Stream blasts remain one of the most consequential unsolved sabotage cases in Europe since the start of Russia’s invasion, with geopolitical implications for energy security, international law, and East-West relations.
