The police on Thursday arrested an Israeli teenager who holds American citizenship in connection with scores of threats to Jewish institutions, including dozens of community centers in the United States, law enforcement officials said.
A spokesman for the police here, Micky Rosenfeld, said the suspect, from the Ashkelon area of southern Israel, had also made threats to institutions in Australia and New Zealand, as well as to at least one commercial airline flight, forcing an emergency landing.
“This is the guy we are talking about,” Mr. Rosenfeld said.
The authorities did not immediately identify the teenager, who they said was Jewish and 19. Other reports put his age at 18. He was expected to appear in court later Thursday.
The suspect’s motives were not immediately clear. He was being questioned by the international investigations unit of the Israeli police.
The arrest took place after a monthslong investigation in cooperation with the F.B.I. and other police and security agencies in the United States and Europe, the Israeli police said in a statement.
“The investigation began in several countries at the same time, in which dozens of threatening calls were received at public places, events, synagogues and community buildings that caused panic and disrupted events and activities in various organizations,” the statement said.
Representatives of the F.B.I. and police organizations from various other countries arrived in Israel to take part in the investigation, the statement said, adding that technology was used to track the suspect down. [...]
