Ulm, 29 May 2026

The Ulm public prosecutor's office filed charges on Friday against three men and one woman for a series of construction foam attacks on vehicles across four German federal states.

The accused, aged 18 to 21, allegedly filled the exhaust pipes of hundreds of cars with construction foam between December 8 and December 11, 2024. The attacks took place in Blaubeuren, Langenau, Neu-Ulm, Berlin, and Schönefeld in Brandenburg.

According to the prosecutor's office, the suspects also placed stickers on the damaged vehicles. The stickers read "Sei Grüner!" and featured an image of then-Federal Economics Minister Robert Habeck.
