Israeli police said Thursday they arrested a U.S.-Israeli citizen who was tied to bomb threats phoned in to U.S. Jewish community centers.
The suspect, who was not named by police, is 19 years old, the Associated Press reports.
Police spokesman Mickey Rosenfeld said the suspect's motives were unclear. Since dozens of Jewish centers have received bomb threats in recent weeks, it is not clear which calls were made by the suspect.
Rosenfeld said the suspect used advanced technology to mask the origin of his calls. He also made threats in New Zealand and Australia.
The FBI and other nations' police assisted in the investigation, Rosenfeld said.
Earlier this month, the FBI arrested Juan Thompson, claiming he made the threats using his ex-girlfriend's name.
