Israeli police are reportedly investigating whether two senior aides to Prime Minister Benjamin Netanyahu harassed a former confidant who turned state's witness in one of the corruption cases held against the premier.
Channel 13 News reported that Ofer Golan and Jonatan Urich were both recently questioned and their phones have been confiscated.

It says Golan hired a van in August to park outside the home of Shlomo Filber, blaring a message, "Be a man – stop lying about Netanyahu."
Filber, the former Communications Ministry director general, agreed to testify against Netanyahu in Case 4,000, which centers on potentially illicit dealings and conflict of interest involving Israeli telecom corporation Bezeq and the Walla news website, which Bezeq owns.
In a statement on Monday, police and justice officials said witness harassment is extremely serious.
Urich reportedly told police the van was a campaign stunt and Netanyahu was not involved.
