Four Suspects Identified Following Sabotage Attack on Berlin Power Lines

Authorities have identified four individuals suspected of involvement in a deliberate sabotage attack on Berlin's electricity infrastructure, which occurred in September 2025. The incident resulted in a significant power outage affecting approximately 50,000 households and 2,000 businesses, primarily in the vicinity of a major technology park in the German capital. The outage caused extensive disruptions, with estimated damages to technology firms ranging from 30 to 70 million euros.

In a large-scale operation led by the Berlin General Prosecutor's Office, police searched 17 properties across Berlin, Hamburg, Düsseldorf, and Kyritz in Brandenburg. Around 500 officers participated in these coordinated raids. The suspects--two men and two women aged between 28 and 36--are under investigation for alleged anti-constitutional sabotage. Despite being identified, none were taken into custody, as current evidence did not meet the threshold required for issuing arrest warrants.

The attack, which occurred on September 9, 2025, involved arson targeting two high-voltage power lines in southeast Berlin. The resulting fire severely damaged the power supply infrastructure. An online statement subsequently claimed responsibility for the incident, citing opposition to the nearby Adlershof technology park and its resident companies specializing in IT, robotics, biotechnology, nanotechnology, aerospace, and security industries.

Authorities attribute the attack to left-wing extremist circles. The Federal Office for the Protection of the Constitution was closely involved in the investigation. Reports indicate that the raids were partly directed at an anarchist group, with links to a publication associated with a small collective from Bavaria also under scrutiny.

Investigators have not identified any connections between these suspects and a separate, similar attack on Berlin's power infrastructure in January. That incident, which led to a longer-lasting outage in the city's southwest, was claimed by groups identifying themselves as the 'Vulkangruppen'. The Federal Criminal Police Office (BKA) is leading the ongoing investigation into the January attack.

During the recent searches, officers confiscated mobile phones, laptops, documents, and other electronic devices from various locations, including several Berlin districts, two apartments in Hamburg, and premises in Düsseldorf and Brandenburg. Some of the targeted sites are known to be frequented by members of the radical left-wing scene, including an anarchist library in Kreuzberg. Police also deployed sniffer dogs and conducted detailed examinations of properties, while a small group of demonstrators protested outside one location in Berlin.

The investigation, led by a specialized task force known as 'EG Spannung' within the Berlin State Criminal Police Office, is focused on charges related to anti-constitutional sabotage, the formation of a criminal organization, and arson. Previous efforts included the temporary closure of sections of Berlin's urban motorway to search for evidence with the assistance of detection dogs.

Government officials have expressed their approval of the intensified law enforcement response. Berlin's governing mayor emphasized the increased pressure on those responsible for the attacks, while the city's interior and economic ministers stressed the importance of protecting critical infrastructure and ensuring that perpetrators are brought to justice. The police union acknowledged the challenges authorities face in securing sufficient evidence to prosecute such acts.

The president of the BKA highlighted a trend of escalating intensity in attacks on public infrastructure by left-wing extremist groups in recent years, referencing both the Berlin incidents and other similar attacks in the Munich area. Authorities remain vigilant, closely monitoring extremist activities and continuing their investigations to prevent further sabotage attempts.
