Police yesterday questioned Netanyahu for five hours at his Jerusalem residence as part of a corruption probe, the second such interrogation in four days.
"It is clear that there is nothing of substance in the suspicions," attorney Jacob Weinroth said in a statement.
Weinroth did not directly refer to the police suspicions against his client, but referred throughout to media allegations.
Among them is a report by privately owned Channel Two television saying police suspect that over the course of seven or eight years Israeli businessman, Hollywood producer and Netanyahu friend Arnon Milchan sent him boxes of expensive cigars with a total value of tens of thousands of dollars.
According to Haaretz Newspaper, Milchan owns a 9.8-per cent stake in Israeli Channel 10 television, a competitor to Channel Two.
