Prime Minister Binyamin Netanyahu was questioned by police on Thursday in connection with two separate investigations into alleged corruption, the police said.

"We confirm that the prime minister was questioned today for several hours at his Jerusalem residence," said a Hebrew language statement, adding that the interrogation was carried out by detectives of the Israel Police's Lahav 433 investigators.

The questioning lasted approximately four hours. This was the fifth time that Netanyahu has been questioned about what are known as Cases 1000 and 2000.

Following the interrogation, Netanyahu wrote on Twitter, "I tell you once again with absolute certainty: There will be nothing - because there was nothing!"

In Case 1000, Netanyahu and his wife are suspected of allegedly receiving illegal gifts from billionaire supporters, including hundreds of thousands of shekels worth of cigars and champagne.

Case 2000 deals with the suspicion that Netanyahu made a deal with Yediot Aharonot publisher Arnon “Noni” Mozes. The deal would allegedy have seen Netanyahu advance legislation to close down the Sheldon Adelson-owned Israel Hayom, in return for more favorable coverage from Yediot Aharonot.

Case 3000, the submarine affair, was not discussed, as Netanyahu is not considered to be a suspect in the case.

Both lawyers close to Netanyahu, Yitzhak Molcho and David Shimron, were interrogated several times this week in connection with the case.
