The decision Monday came after an appeal by investigative journalist Raviv Drucker of Channel 10 TV. Netanyahu backer Adelson owns the pro-government daily Israel Hayom. Police are investigating Netanyahu in two cases.
One reportedly concerns Netanyahu's alleged attempts to strike a deal with the publisher of the Yediot Ahronot newspaper group to weaken Israel Hayom — Yediot's main competitor — in exchange for more favorable coverage of Netanyahu by Yediot.
Israeli police revealed last week that Netanyahu is suspected of crimes involving fraud, breach of trust and bribes. Netanyahu has repeatedly denied wrongdoing.
