He and other former company officials are being investigated, however, for the administrative offence of breaching their corporate supervision duties, the prosecutors said in a statement. For a story on the prosecutors statement click on

Following is a chronology of the development of corruption investigations involving Siemens.

He is considered a potential witness, not a suspect.

November 23 - Siemens sets up an anti-corruption task force.

December 11 - Siemens cuts its reported 2005/06 net profit by 73 million euros in light of the affair and hires outsiders to examine its compliance systems and rules.
