German prosecutors confirmed Thursday that a Ukrainian national has been arrested in Italy on suspicion of coordinating the 2022 sabotage of the Nord Stream pipelines, one of the most damaging strikes ever carried out against European energy infrastructure. The September blasts ruptured Nord Stream 1, which had carried 55 billion cubic meters of Russian gas annually to Germany, and left Nord Stream 2 inoperable before it could begin operations.
The suspect, identified as Serhii K., was detained by Italian police in the Rimini province under a European arrest warrant. German prosecutors allege that he played a coordinating role in a group that rented a yacht in Rostock using forged documents. The vessel was allegedly used to reach waters near Bornholm, where divers placed explosive charges on the pipelines. He faces accusations of conspiracy to cause an explosion, anti-constitutional sabotage, and destruction of critical infrastructure.
The destruction of Nord Stream 1 cut off one of Europe’s largest gas arteries, forcing utilities to increase LNG imports from the United States, Qatar, and West Africa. Spot prices surged as traders scrambled for cargoes, and governments accelerated storage programs to safeguard winter supply. The loss of both pipelines reshaped Europe’s energy balance, reinforcing long-term plans to diversify away from Russian pipeline flows.
Responsibility for the sabotage has remained disputed. Moscow has repeatedly accused Western governments, while Kyiv has denied any involvement.
Denmark and Sweden closed their investigations in 2024 without indictments, leaving Germany’s inquiry as the only active probe. Berlin’s Justice Ministry described the Italian arrest as a significant investigative advance in a case that has weighed on European energy security since 2022.
Berlin has meanwhile hardened its stance on future Russian gas flows. In late May, German officials pledged to do “everything possible” to block any revival of Nord Stream, reinforcing a policy shift that cements LNG and alternative pipeline supplies as the backbone of Europe’s energy mix.
