According to the German news agency dapd, Berlin Interior Minister Frank Henkel told a parliamentary committee Wednesday the state's domestic spy chief, Claudia Schmid, had resigned.
Schmid came under fire last week after her agency mistakenly shredded dozens of files on far-right extremists. On Tuesday she acknowledged that files on the far-right "Blood and Honor" group were also shredded in 2010.
None of the files, however, appear to relate to the far-right National Socialist Underground, which is suspected of killing 10 people. Four other top Germany security officials have resigned this year due to blunders in the NSU investigation.
