A source in law enforcement indicated that many of Ganor's claims will also require the assistance of international investigators.
Until now, the majority of Ganor's testimony involves David Shimron, Prime Minister Benjamin Netanyahu's personal attorney, and former Commander of the Navy, Eliezer Marom.
Ganor has indicated that both men were due to receive millions of shekels in commission for their help in getting the purchase deal for German submarines pushed through.
Ganor also alleged that during Marom's tenure as head of the Navy, he maintained good relations with the German consortium and even acted to have them replace their representative in Israel.
Additionally, according to Ganor, following his retirement from the navy, Marom agreed to consultancy positions worth millions of shekels.
Shimron, who was allowed to travel abroad following his release from house arrest, is expected to receive a summons to the police's Lahav 433 headquarters in order to answer questions related to Ganor's testimony.
Shimron's attorneys have already denied claims made by Ganor that Shimron was due to receive nearly $10 million for the submarine deal.
Similarly, Marom also denies any wrongdoing, claiming that he only received roughly NIS 370,000 from Ganor for advice he gave from 2014-2016, after he had already been released from the Navy.
Police suspect Marom acted to have Ganor represent ThyssenKrupp in Israel while he was still in command of the Navy, but only received the money after he was released.
