The former chief of staff for Prime Minister Benjamin Netanyahu was questioned a second time under caution on Monday.
Ari Harrow was taken for questioning last week upon his arrival at Ben Gurion International Airport, although he was told he was not being arrested.
After 14 hours of interrogation “under caution” — implying he was indeed a suspect in the unspecified investigation — he was released to five days of house arrest.
The interrogation was carried out in connection with a probe into allegations of fraud in an initial investigation into the activities of Prime Minister Benjamin Netanyahu and his family, as well as other government figures.
A spokesperson for Israel Police said the National Fraud Investigation Unit last week asked Harrow to provide testimony about Netanyahu’s alleged financial misappropriations.
Earlier last week Israeli Attorney-General Avichai Mandelblit ordered an initial probe into the prime minister’s actions as part of the wider investigation of financial activity by government officials.
Harrow served as chief of staff to Netanyahu in 2014.
