Federal authorities have arrested and charged a man in St. Louis who they say is responsible for making at least eight threats against Jewish schools and organizations across the U.S.

The threats were allegedly part of the suspect's larger cyberstalking campaign against a woman with whom he once had a romantic relationship, the U.S. Attorney's Office for the Southern District of New York said.
