In Case 4000, police are investigating suspicions Bezeq majority shareholder Shaul Elovitch and Netanyahu had a quid pro quo relationship in which Bezeq enjoyed regulatory benefits in return for favorable coverage of the Netanyahu family on Walla! News, which is owned by the telecommunications giant.
It is believed Harow has already provided the police with relevant information about Netanyahu's relationship with Elovitch, to which he was exposed while working as Netanyahu's bureau chief.
Netanyahu himself is expected to be questioned in the case on Friday, likely under caution, as well as provide testimony in the submarine affair, Case 3000, in which he is not a suspect.
The police asserted Sunday night that despite the apparent coordination between Israel Securities Authority representative Eran Shacham-Shavit and the Tel Aviv Magistrate's Court judge overseeing the Bezeq Affair, Ronit Poznanski-Katz, the case would not be affected, insisting that "the evidence will prevail."
Judge Alaa Masarwa, who replaced Poznanski-Katz on the case, will hear a request Monday morning by the six suspects arrested in the case—Elovitch, his wife Iris and son Or, media adviser Nir Hefetz, Bezeq CEO Stella Handler and Bezeq executive Amikam Shorer—for an immediate release from custody in the wake of the developments concerning Poznanski-Katz and Shacham-Shavit.
