German federal prosecutors filed charges on July 1 against a Ukrainian national known as Serhii K, accusing him of orchestrating explosions that severely damaged the Nord Stream 1 and 2 gas pipelines in September 2022 near Denmark's Bornholm island [1, 2, 3].

The blasts cut off key Russian gas routes to Europe months after Russia's invasion of Ukraine in February 2022. Prosecutors allege Serhii K helped coordinate a team that used the sailing yacht Andromeda to place explosive devices near Bornholm [2, 3]. Although suspected to be the on-board coordinator and team leader, he was reportedly not a diver or bomb expert [2, 3].

The pipelines ended at Lubmin in Mecklenburg-Vorpommern, Germany, and their loss significantly impacted Germany's energy security. German courts claim jurisdiction because of this territorial link [2].

Serhii K was arrested on August 21, 2025, in Italy's Rimini province and extradited to Germany on November 27, 2025, where a German judge put the arrest warrant into effect [1, 2, 3]. Prosecutors say he used forged identity documents to charter the yacht used in the sabotage operation [3].

The 50-year-old suspect denies involvement, claiming he was serving in the Ukrainian armed forces and was in Ukraine at the time of the blasts [1, 3]. His lawyer Nicola Canestrini expressed confidence he will be acquitted at trial in Germany [1].

The indictment was served and made public by German authorities on July 1 or 2, with media reporting following soon after [2, 3]. Court proceedings are expected as the case moves forward.
