JERUSALEM — The Israeli police on Thursday recommended the indictment of one of Prime Minister Benjamin Netanyahu’s closest confidants and three others from his inner circle in a sprawling bribery case involving the multibillion-dollar purchase of submarines and missile boats from Germany.

Mr. Netanyahu was not a suspect in the naval-acquisition scandal, which has been called Case 3000, and in fact he was cleared months ago, though he was questioned. The police have recommended criminal bribery, fraud and breach of trust charges against Mr. Netanyahu in two other corruption investigations.

The police said they had sufficient evidence to charge David Shimron, a second cousin of Mr. Netanyahu’s as well as his personal lawyer, with bribery and money laundering.

Mr. Shimron, they said, had exploited his “status and closeness to the prime minister” to promote the submarine purchase on behalf of Michael Ganor, an Israeli agent working for ThyssenKrupp Marine Systems, the shipyard that build the vessels. In exchange, Mr. Shimron was paid a “reward for success” of nearly $75,000 for “opening doors” and influencing officials in favor of the deal, the police said. Mr. Ganor turned state’s witness in 2017.
