German industrial group Thyssenkrupp has not found any evidence of corruption in its handling of a $2 billion contract to sell submarines and naval patrol craft to Israel, it said in a statement on Tuesday. "Based on the investigative measures we were able to carry out, we found no concrete indications of corruption – either with regard to submarine projects, or in connection with the procurement of corvettes," it said. Thyssenkrupp declined to comment on Israeli media reports that the signing of the deal had been postponed in the wake of Israel’s ongoing corruption case. Officials at both the German chancellery and defense ministry also declined to comment on the investigation, calling it an internal Israeli matter. The German firm only suspended relations with its agent for the deal, Mickey Ganor, the leading suspect in Israel’s pmgoing corruption investigation.
