Searches continue after Klette was arrested. Investigators found explosives, a rocket-propelled grenade and firearms in the apartment.

Klette is said to have fired at least 250 shots at the US embassy in Bad Godesberg with RAF members in February 1991. For decades, the left-wing extremist organization Red Army Faction (RAF) was the epitome of terror and murder in the west of still divided Germany. The investigators are still receiving information from the public, but there are also anonymous tips or fake news.
