Grenade in Klette's apartment: Used until the night. Ammunition, weapons, a grenade and other dangerous items were apparently found in the apartment of former RAF terrorist Daniela Klette.

Investigators arrested the 65-year-old in Kreuzberg on Monday evening. Klette is accused of having, together with Burkhard Garweg and Ernst-Volker Staub, carried out an explosive attack on the Weiterstadt correctional facility in Hesse in March 1993. Police are examining further measures at the BVG warning system.
