FRANKFURT -- The Frankfurt auto show, which opens next month, is stepping up security checks to prepare for potential disruption by climate activists who are calling for people to join anti-car protests.
Police are already investigating a group calling itself "Rocks in the Gearbox" after more than 40 luxury vehicles were vandalized at a car dealership in Kronberg on the outskirts of Frankfurt earlier this week, adding to a string of anti-auto protests.
Ahead of the car show, Germany's auto industry association, the VDA, has sought to defuse anti-car sentiment by inviting environmental activists from Greenpeace and Deutsche Umwelthilfe to a panel discussion on Sept. 5 in Berlin, where they along with executives from Daimler and BMW and the VDA will discuss the climate crisis and mobility of the future.
The Frankfurt show, known as the IAA, is due to take place from September 12 to 22.
"We are in close contact with the security authorities just as we are at every IAA. Entrance controls will be tightened, given that there may be spontaneous rioting at the show," VDA spokesman Eckehart Rotter told Reuters.
Environmental groups, including one called "Rocks in the Gearbox", have appealed to the public to join protests in Frankfurt on September 14, prompting the VDA to warn car show visitors to expect longer queues at security checkpoints.
Police in Wiesbaden on Thursday said they were investigating "Rocks in the Gearbox" after the group claimed responsibility for vandalizing Jaguars, Land Rovers and Aston Martins at the car dealership on Monday.
Windshields and windows, hoods and panels were smashed with metal objects and the two glass doors at the car dealership were broken, a spokesman for the Wiesbaden police told Reuters.
"They used hammers and crowbars and we are investigating a group claiming responsibility," the spokesman said.
"Rocks in the Gearbox" released a statement on Monday saying: "In two weeks Frankfurt will once again launch a propaganda show where the outmoded, climate and environment destroying transportation system is hyped."
"We want to expose this show for what it really is: profits made on the backs of the poorest and at the expense of future generations ... We think it is time to throw rocks into the gearbox of capitalist and automotive profit logic."
The statement called for more scrutiny of working conditions in related industries, including freight, cotton and rubber production as well as for people mining rare earths for electric car batteries and electronics.
Earlier in August, climate activists had occupied railway lines supplying Volkswagen's Wolfsburg factory, according to police in Wolfsburg-Helmstedt.
"We have opened a probe investigating potentially dangerous disruption of rail and shipping transportation," a police spokesman told Reuters.
