A Jewish teenager with American and Israeli dual citizenship was arrested Thursday for a string of recent bomb threats that terrorized Jewish community centers in three continents, reports the New York Daily News.

Israeli police announced the arrest of a 19-year-old for phoning in the phony threats, but refused to release his name. He shielded his face from media as guards escorted him out of a justice court in Rishon Lezion.

His lawyer told reporters the teen suffers from a "very serious" medical condition that kept him out of school and the Israeli army, and may have affected his behavior.

His motive for the alleged scare spree is a mystery and it's unclear how many threats he may be tied to. Police said he used sophisticated camouflage technology to disguise his voice and location when making calls.

Israeli authorities worked with the FBI and other international law enforcement to crack the case. During his arrest, the teen tried to grab an officer's gun until another officer stopped him, police said.
