A dual US-Israeli citizen from Ashkelon has been arrested on suspicion of standing behind most of a series of bomb and other threats to Jewish communities ranging from the US, Europe, Australia and New Zealand over the past six months, The Jerusalem Post has learned.

As of Thursday, with a gag order on the probe lifted by the Rishon Lezion Magistrate’s Court, which extended his detention, sources indicate that most of the cases of threats against Jewish communities and organizations, though not all, led investigators back to Israel…

The suspect used complex methods to shield himself from identification, and law enforcement had to use a variety of their own complex methods to find him…

It is unknown how many others might have worked with the suspect, but it is believed that he was the main operator of the scare-spree and might have even acted completely on his own.
