The Jewish Israeli-American arrested this week on suspicion of making a host of bomb threats on Jewish institutions worldwide has been making such cyberattacks for two years, but only recently was his capture given high priority, according to police sources.

The sources attributed the turnabout to pressure from United States President Donald Trump. A few weeks ago, after Trump announced that the FBI would do everything in its power to catch the perpetrator, the agency sent 12 investigators from its cybercrime unit to Israel to assist the Israeli investigation.
