German police arrest suspect in sabotage attacks on electricity grid

German police have arrested 48-year-old Daniel V. near the Weisweiler power station, ending a dayslong manhunt. The suspect, who was carrying explosives, is accused of using homemade rockets to shoot conductive wires across high-voltage lines, causing short circuits in three states. While the attacks initially sparked fears of Russian hybrid warfare following a recent explosive drone incident at Leipzig/Halle Airport, officials now attribute the sabotage to domestic climate extremism.

Arrest of climate extremist suspect

• ▪German police arrested a 48-year-old man, identified by local media as Daniel V., near the Weisweiler power station in western Germany on September 8, 2026.
• ▪Prior to the arrest, an arrest warrant had been issued for the 48-year-old suspect by the Cottbus Public Prosecutor’s Office following a dayslong search.
• ▪The suspect, Daniel V., was carrying explosives at the time of his arrest, and police subsequently discovered a nearby tent containing additional explosive charges.

Homemade rocket sabotage methods

• ▪On September 7, 2026, police discovered several launch devices on a high-voltage power line near the Weisweiler plant alongside a letter claiming responsibility.
• ▪The suspect is accused of using homemade rockets to shoot thin conductive wire across high-voltage power lines to cause short circuits.
• ▪In Saxony, police discovered 21 launch devices near high-voltage power lines on September 4 and September 5, 2026.

Power grid targets across states

• ▪An attack at the Bergheim power substation near Cologne knocked five power generation units offline for several days, though no widespread power outages occurred.
• ▪A September 1, 2026 attack at a substation near the Jänschwalde coal-fired power plant in Brandenburg involved more than 20 homemade rockets and caused two short circuits.
• ▪The sabotage attacks targeted electricity infrastructure across three German states: North Rhine-Westphalia, Brandenburg, and Saxony.

Climate activism motive letters

• ▪German Interior Minister Alexander Dobrindt characterized the attacks as "climate terrorism" or "climate extremism" carried out by a lone offender.
• ▪The handwritten letters, signed with the first name Daniel, contained non-public details about the attacks and listed a residential address in Gevelsberg.
• ▪The suspect justified the sabotage in letters claiming responsibility, stating that generating electricity from fossil fuels is a crime and targeting states where lignite is mined.

Initial Russian hybrid warfare fears

• ▪The sabotage initially sparked fears of a Russian hybrid campaign targeting German critical infrastructure amid high alert over previous drone incidents.
• ▪The German government previously blamed Russia for an August 4, 2026 attempted attack at Leipzig/Halle Airport using an explosive-laden drone near a Ukrainian cargo plane.
• ▪Russian President Vladimir Putin responded to the Leipzig airport allegations by accusing Germany of planting evidence to blame Moscow.
