German police are investigating a nighttime fire at an electrical substation in central Berlin. Authorities discovered a cut fence near the substation in western Germany, as reported by Bild. This incident follows a series of attacks on power substations across Germany last week, which officials are treating as sabotage. Currently, a search is underway for a 48-year-old man who has claimed responsibility for the attacks in letters to authorities. The investigation aims to determine if the Berlin fire is linked to the previous incidents and identify any potential coordinated effort to disrupt Germany’s power supply. No injuries have been reported, but the incidents have raised concerns about the security of critical infrastructure.
