The police are hunting a suspected sabotage activist in Hambacherskogen

A large number of police resources are involved on Sunday in the hunt for the 48-year-old man who is suspected of a series of acts of sabotage in Germany.

On Friday, the police carried out a search of the man's home, but the suspect is still at large. The hunt is now concentrated on the large Hambach Forest in the state of North Rhine-Westphalia, where the 48-year-old is believed to be. The police urge the public to contact them if they have seen or heard anything. The suspect was last seen on a bicycle.

In the German media, the suspect is described as a climate activist. The sabotage actions have taken place in several parts of the country, but what the affected states have in common is that they are characterized by mining and mining of lignite, writes the newspaper Bild.

After an attack on a substation in Brandenburg earlier this week, local police received a letter in which the 48-year-old claims responsibility. The letter is deemed genuine and must be signed with his name and address.

According to the German newspaper Focus, he has sent another letter in which he also takes on other attacks.

"Fossil fuels are a crime that causes endless suffering," writes the 48-year-old.

The Hambach Forest, where the man is believed to have fled, has long been a source of conflict in North Rhine-Westphalia. In the mid-1970s, large parts of the forest were cut down to make way for an open pit for coal mining. Since 2012, activists have occupied parts of the remaining natural area, which today is estimated at around 500 hectares.
