"When police investigators believe such delusional and fictitious claims that the prime minister was acting against them personally and sent private investigators against them, how could they objectively investigate and submit recommendations against him?" he wrote in a Facebook post. "We are amazed to learn this is exactly what happened in the investigation of the prime minister."
Netanyahu's onslaught follows an interview given by Police Commissioner Roni Alsheikh to the investigative TV show Uvda, during which he claimed that "powerful" elements had tried to collect information about police officers involved in the investigations against the prime minister.
"First, we learned of a letter written by the head of the investigative unit, (Roni) Rittman, to (then) Attorney General Weinstein, in which Rittman's lawyers implied that the prime minister had sent the female officer who filed a sexual harassment complaint against (Rittman)," Netanyahu wrote on Friday.
He asserted that Rittman, the head of the Anti Fraud Unit, should have recused himself from the investigations against the prime minister.
"You decide: what does this say about the integrity of the investigation, and what does this say about the nature of the recommendations?" Netanyahu concluded.
