An arrest warrant has been opened at the Federal Court of Justice against the ex-RAF terrorist. She is already in custody - for robbery.

But Germany's highest prosecutor, the Federal Prosecutor's Office, is also investigating Daniela Klette. It involves causing an explosive explosion and attempted murder in crimes in the early 1990s. Klette was caught in Berlin at the end of February after more than 30 years underground. The Verden public prosecutor's office is investigating several robberies against the 65-year-old.
