WEISWEILER, Germany — German police arrested a 48-year-old man on September 8 on suspicion of carrying out or attempting a series of attacks on electricity infrastructure across three states, ending a dayslong search that began after authorities and news organizations received responsibility letters.
The suspect was identified under German privacy practice as Daniel V. Police detained him near the Weisweiler power plant in North Rhine-Westphalia, roughly 30 miles west of Cologne. Authorities said he carried explosive devices and did not resist arrest. A nearby tent contained additional explosive charges that bomb-disposal specialists were examining.
The arrest and recovery of suspected devices are established procedural facts. Daniel V. has not been convicted, and responsibility for each incident, the motive and whether anyone else was involved remain matters for investigation and court proceedings.
Attacks and attempted attacks in three states
The investigation includes a September 1 attack near the Jänschwalde coal-fired power plant in Brandenburg. Prosecutors said overhead lines at a substation were targeted and several improvised explosive devices were found, including devices that failed to function.
Hours later, a short circuit disabled power lines at a Bergheim substation near Cologne, knocking five electricity-generation units offline. Officials said conductive material appeared to have been launched onto high-voltage equipment.
In Dormagen, south of Düsseldorf, a passerby found pipes fitted with cables and timers aimed at a substation. Police later located two launch devices. Additional incidents or suspected attempts were reported in Saxony and near Weisweiler.
The Associated Press reported that investigators accuse the suspect of using homemade rockets to fire thin wires across high-voltage lines, producing short circuits. Responsibility letters reportedly described the actions as opposition to electricity generation from fossil fuels, particularly lignite.
Explosives recovered during arrest
Police said the suspect possessed explosives when officers arrested him. They also searched the surrounding area for undiscovered launch or detonation devices while specialists examined charges found in the tent.
A Cottbus court had issued an arrest warrant the previous Friday. The Cottbus prosecutor’s office is investigating suspected offenses involving causing an explosion and disrupting public utilities, and authorities said additional charges were being considered.
The cases in North Rhine-Westphalia, Brandenburg and Saxony had not yet been formally consolidated when Reuters reported the arrest. Investigators must still determine which incidents can be linked through physical evidence, communications or other proof.
Officials differ on how far to characterize motive
Federal Interior Minister Alexander Dobrindt earlier described the attacks as a likely case of “climate extremism,” while acknowledging uncertainty about whether the suspect acted alone, with accomplices or for another party. North Rhine-Westphalia Interior Minister Herbert Reul said after the arrest that current evidence pointed toward a lone actor.
Saxony Interior Minister Armin Schuster urged officials not to draw premature conclusions. He described the responsibility letter as unusual and said possible explanations still included left-wing extremism, climate-related motivation or action on behalf of another party. Those official assessments are not judicial findings.
Authorities initially did not exclude foreign involvement because Germany was already on high alert following other alleged sabotage activity. AP reported that officials later considered the grid incidents more likely to involve a single activist. No evidence reviewed for this article establishes involvement by Russia or another foreign government in the power-grid case.
What remains unresolved
Investigators had not publicly released a complete list of affected sites, the full damage and outage totals, forensic results from the recovered devices, or evidence linking the suspect to every event. It also remained unclear whether a court had completed the next detention hearing and whether prosecutors would combine the state investigations.
The suspect is presumed innocent. Responsibility letters and official suspicions must be tested against forensic and other evidence before guilt can be established.
