Two people were being questioned under caution by police on Thursday, on suspicion of connection to threats made against Attorney General Avichai Mandelblit.
Dozens of messages sent to Mandelblit’s phone in recent days included death threats against him and his family.
On Wednesday, Mandelblit filed a police complaint on the matter.
A statement from the Justice Ministry said Mandelblit provided testimony to police investigators and that the messages appeared to be part of an organized campaign.
