A 31-year-old man was arrested Friday morning on suspicion of making bomb threats to seven Jewish community centers around the country and threatening the Anti-Defamation League's New York headquarters.
Federal law enforcement officials said the man, Juan Thompson, was arrested in St. Louis.
Thompson also faces charges of cyberstalking of an ex-girlfriend and making some of the threats in her name, according to the FBI and the U.S. attorney's office in the southern district of New York.
Thompson was expected to appear in court in Missouri on Friday.
Jewish institutions across the country have seen more than 100 bomb threats come in to community centers, schools, ADL offices and other Jewish centers in more than 30 states since Jan. 4.
At least three cemeteries, including one outside St. Louis, also have been vandalized in recent weeks, with headstones toppled. The other two cemeteries are in Philadelphia and Rochester, N.Y. In addition, a synagogue in Indiana was struck with a bullet this week. Nobody was injured.
Thompson does not face charges for threats or attacks beyond the seven calls to Jewish centers and the ADL headquarters.
Federal officials said they are still investigating the other incidents.
