BERLIN (AP) — German police raided 15 properties linked to the Last Generation climate activist group Wednesday, seizing assets as part of an investigation into its finances in a sign of growing impatience with disruptive protest tactics also seen in other European countries.

Members of the group have repeatedly blocked roads across Germany in an effort to pressure the government to take more drastic action against climate change. In recent weeks, they have brought traffic to a halt on an almost daily basis in Berlin, glueing themselves to busy intersections and highways. Over the past year, they have also targeted various artworks and exhibits.

The raids, ordered by Munich prosecutors, come days after Chancellor Olaf Scholz said that he thought it was “completely nutty to somehow stick yourself to a painting or on the street.” Leading figures with the environmentalist Green party, part of his governing coalition, have also said the group’s actions are counterproductive.

A spokesperson for Last Generation said that the police searches had hit the group and its supporters hard, but that it wouldn’t let up its activities.

“They make us afraid, but we must not be frozen by fear,” Aimee van Baalen told reporters in Berlin.

“The German government is right now driving us toward climate hell with its eyes wide open. It is even stepping on the gas pedal,” she said. “We must continue to resist now, because we need to loudly demand that lives be protected.”

Hundreds of people joined a protest march in Berlin against the raids and further rallies were planned in other German cities.

One protester, Chaim, who declined to give his last name for fear of legal repercussions, said he felt the crackdown against climate activists was politically motivated. “It’s wrong and dangerous,” he said.

Last Generation has acknowledged in the past that its protests are provocative, but argues that by stirring friction it can encourage debate about climate change and the policies necessary to stop it.

Germany’s top court ruled two years ago that the previous government was placing too much of the burden from global warming on young people, prompting then-Chancellor Angela Merkel to sharpen climate targets. Experts say that while Germany now has some of the most ambitious targets for cutting emissions of planet-heating greenhouse gas, the country isn’t on track to meet them.

The investigation by Munich prosecutors is focused on seven people, ranging in age from 22 to 38, who are suspected of forming or supporting a criminal organisation. The investigation was launched following numerous criminal complaints from the public over the past year, prosecutors said.

The Bavarian inquiry adds to an investigation launched last year by prosecutors in Neuruppin, outside Berlin, over actions against an oil refinery in eastern Germany. That investigation is also considering suspicions that Last Generation activists formed a criminal organisation, a label that some conservative-leaning regional officials have backed.

Munich prosecutors said that the people under investigation are accused of organising and promoting a campaign to “finance further criminal offences” by the group, and collecting at least 1.4 million euros ($1.5 million). Two of them also are suspected of trying to sabotage an oil pipeline that connects the Bavarian city of Ingolstadt with the Italian port of Trieste in April 2022.

Wednesday’s searches, accompanied by orders to seize two bank accounts and other assets, aimed to secure evidence on the membership structure of Last Generation and on its financing. There were no arrests.

Other environmental groups such as Extinction Rebellion and Greenpeace criticised the raids and accused the government of trying to criminalise peaceful climate protesters.

Carla Hinrich, a prominent member of Last Generation who has taken part in numerous televised debates with German politicians, said she was woken by police who entered her apartment with guns drawn. Prosecutors confirmed that her flat was raided but declined to comment on police tactics.
