"Criminally relevant behaviour, in particular acts of bribery, were not established by the public prosecutor's office," said a spokesperson for ThyssenKrupp Marine Systems in South Africa.
Having established that there was no case against anyone under investigation, the public prosecutor's office in Düsseldorf closed the investigation without sanction or cash settlement.
The Germans informed the South African and Angolan authorities of the outcome and withdrew all requests for legal support made previously.
The German investigation was started in 2006 to establish whether employees of the ThyssenKrupp Group, among others, were guilty of criminal behaviour in connection with the sale of four ships to the South African navy in the late 1990s, and an intended sale of ships to the Angolan navy.
At the same time, in different investigative proceedings not substantively connected with the above-mentioned matter, penal orders were issued against two former employees of the ThyssenKrupp Group, accused of fraud and or abetting fraud.
National Prosecuting Authority spokesperson Tlali Tlali said he had heard about the decision, but was not in a position to comment.
