Overview
- The formal indictment, which prosecutors filed on June 30, charges a Ukrainian national identified as Serhii K. with attacking civilian energy infrastructure, causing explosions, destroying structures and acting as an accomplice to war crimes.
- Prosecutors say the accused led a seven-person team that used the chartered sailing yacht Andromeda to transport and attach military-grade explosives to the seabed pipelines, with investigators reporting traces of HMX and RDX on the vessel.
- The suspect was arrested in Italy in August 2025, extradited to Germany in November 2025 and has been held in pretrial detention in Hamburg while he denies the allegations.
- German authorities have identified up to seven suspects in the case but at least one is reported dead and another is blocked from extradition by a Polish court, creating cross-border legal hurdles for the prosecution.
- The charges close a long-running investigation that left three Nord Stream lines unusable, raised questions about state responsibility for attacks on civilian infrastructure and could set a legal precedent for prosecuting such acts in wartime.
