Jerusalem, March 27 (RHC) -- Israel's Prime Minister Benjamin Netanyahu and his wife and son were questioned by the police on Monday over corruption investigation that also involves the country's largest telecom company.

A police spokesperson confirmed that Netanyahu was questioned at the official Prime Minister's Residence in Jerusalem. His questioning lasted about four hours.

In the same time, his wife, Sara Netanyahu, was separately questioned at the offices of Lahav 433 anti-corruption unit in Lod, outside Tel Aviv, and their son, Yair Netanyahu, was questioned at the office of the Israel Securities Authorities.

An earlier statement said that Shaul Elovitch, the control-holder of Bezeq telecom and a major suspect in the affair, was also questioned.

The Netanyahus are suspected of being involved in a bribery case, dubbed "case 4,000," in which Elovitch's Bezeq received regulatory and financial benefits from the Communication Ministry, during Netanyahu's term as the communication minister. In exchange, Netanyahu received positive coverage in Walla, a news site controlled by Elovitch.
