Israeli Prime Minister Benjamin Netanyahu was on Friday questioned for the first time by Israeli police over a corruption case involving the country's largest telecommunications company Bezeq, according to Israel Radio.
Detectives arrived at the prime minister's home at 9 am local time (8 am CET), said AFP news agency.
Netanyahu's wife, Sara, gave a statement to investigators at the national fraud squad headquarters near Tel Aviv at the same time, media said.
Police did not officially confirm that they had started questioning.
Known as Case 4000, police alleged Bezeq Israel Telecom owners provided favourable coverage of Netanyahu and his wife on a news website they controlled in return for favours from communications regulators.
The controlling shareholder of the company, Shaul Elovitch, is currently in police custody, along with a former Netanyahu spokesman.
Both deny any wrongdoing.
The prime minister is also a suspect in two other graft probes, which pose a threat to his four-term political survival.
Netanyahu was re-elected in 2009 and has also held several ministry posts.
The Israeli prime minister denies any wrongdoing in all the cases.
