Several German companies are under investigation for alleged involvement in Iran's disputed nuclear program, a German magazine reported Saturday.
Police searched the premises of eight firms as well as private homes on February 8 as part of the investigation, the Spiegel weekly said in an article released before its publication Monday.
Horst Salzmann, a spokesman for federal prosecutors, declined to comment on the report.
According to Spiegel, one firm from Cologne was involved in a planned delivery to Iran of equipment to detect radiation contamination on clothes and human skin.
