Ynet reports that a suspicious envelope arrived at the Prime Minister's Residence on Balfour Street in Jerusalem this evening (Tuesday). Hazardous materials teams from the fire department were called to the scene.

On Saturday night, a young man from Kfar Saba was arrested on suspicion of placing the threatening letter against Prime Minister Benjamin Netanyahu on the grave of his brother, Yoni Netanyahu, on Mount Herzl in Jerusalem.

The young man, 26 years old, was arrested by the Israel Police's Lahav 433 investigation unit at the end of a joint investigation with the Israel Security Agency (Shin Bet), a day after receiving the report about the letter.

The letter was found on Yoni Netanyahu's grave by the workers of the Mount Herzl site. Among other things, it reads, "The clock is ticking back until the 28th of Tishrei this year when your brother, the son of ----, thinks he will reach the age of 74 - to be clear, this is a first-degree threat."

The threatening letter also read, "Bibi, you are no better than Sharon. Sharon had a stroke and was in a coma for eight years. I wish worse things for you. Your tasks are: a. to conquer Gaza, b. to bring back the body of Hadar Goldin and the other captives. The clock is ticking back. You have more than three and a half months left."

Last week, a Beit Shemesh resident in his 20s was arrested on suspicion of threatening Netanyahu after he wrote in a WhatsApp group of right-wing activists "that everyone should carry a weapon and hit Bibi with a bullet in the head. Whoever wants to buy a weapon should send a message - that the law is about our lives and we are not interested." The police are investigating the case.
