A St. Louis man was arrested on Friday for making threats against at least eight Jewish Community Centers across the United States.

Juan Thompson is accused of calling in bomb threats to multiple JCCs and the headquarters of the Anti-Defamation League. According to authorities, Thompson made the calls as part of an effort to harass an ex-girlfriend, and used her name when making the threats.

According to the FBI’s official complaint, Thompson emailed the ADL on February 21 to say that the woman was “behind the bomb threats against the jews. She lives in nyc and is making more bomb threats tomorrow.” He allegedly made a similar threat to JCCs in San Diego and Dallas.

Thompson also allegedly emailed threats anonymously to other Jewish institutions accusing himself of planting bombs, and then tweeting that his ex-girlfriend “sent a bomb threat in my name & wants me to be raped in jail.” He even tweeted sympathy for victims of the bombing threats:

Another week, another round of threats against Jewish ppl. In the middle of the day, you know who's at a JCC? Kids. KIDS.

Thompson worked as a journalist for the online publication The Intercept from late 2014 to early 2016, before being fired for fabricating quotes and using fake email accounts to impersonate people, including his own boss. He is being charged with one count of cyberstalking, which carries a maximum sentence of five years. He is scheduled to appear in court in St. Louis later on Friday.

Thompson is believed to be a copycat and not responsible for the vast majority of the bomb threats, which have targeted more than 100 Jewish institutions across the United States and Canada so far this year. No bombs were found at any of the threatened locations.
