On Wednesday night, power cables burn near the future Tesla plant near Berlin - the police are also investigating a possible political motive.
Arson cannot be ruled out, said a police spokesman on Wednesday morning.
"The LKA investigation team is currently on site and is investigating the crime scene."
A letter of confession appeared at noon. Under the author's name “Vulkangruppe” it says: “On the night of May 25th to 26th, 2021, we cut the power supply to the construction site of the Tesla Giga factory in Grünheide near Berlin by setting fire to six high-voltage cables laid above ground have. ”This is followed by criticism of the carmaker. "Tesla is neither green, ecological nor social," says the letter published on the Indymedia.org platform. "We check whether there is something to it," said Joachim Lemmel, spokesman for the State Criminal Police Office (LKA) Brandenburg.
The power cables in a forest about 500 meters from the carmaker's plant had burned on Wednesday night.
The arm-thick cables supply, among other things, the construction site of the car factory that is currently being built in Grünheide (Oder-Spree district).
Despite the fire, the cables are still functional, the police said in the morning.
The energy supplier Edis announced in the afternoon: “Immediate supply interruptions have not been necessary so far.” The supplier's emergency services have been on site since the early hours of the morning to assess the damage and to initiate and coordinate further necessary steps, said spokesman Danilo Fox.
