A former leftist journalist fired for making up stories was arrested Friday morning on suspicion of being behind at least some of the recent bomb threats against Jewish institutions across the country, according to the Chicago Tribune.

This arrest comes after a wave of bomb threats at Jewish centers and schools across the country. Headstones have also been vandalized at Jewish cemeteries in Missouri, Pennsylvania and, most recently, Upstate New York.

The FBI arrested Juan Thompson, 31 in St. Louis, according to the U.S. Attorney's Office in the Southern District of New York. The FBI alleges Thompson made the threats in an attempt to frame his ex-girlfriend.

Thompson had been fired from the left-wing website Intercept for fabricating quotes and misleading colleagues to cover his tracks. In an editor's note last year, the publication said Thompson had engaged in "a pattern of deception" and wrote that he created fake email accounts to impersonate people.

The Intercept released a statement this morning in the wake of the arrest, confirming that Thompson is a former employee:

The Tribune has more:

Thompson has been charged with cyberstalking for allegedly communicating at least eight threats to Jewish Community Centers as part of a sustained campaign of harassment targeting a woman. He is expected to appear in court later Friday.

The woman and Thompson had been in a romantic relationship, and after their relationship ended, he began sending defamatory emails and faxes to her workplace, making false reports of criminal activity by her and making threats to the Jewish centers in her name. Authorities also said some of his threats were made in his own name as a way to show the woman was trying to frame him.

The criminal complaint filed in federal court points to his Twitter page, where he rails on his ex-girlfriend as a nasty "nasty/racist #whitegirl." In one tweet, Thompson accused the woman of harassing and threatening him before saying she had framed him for a bomb threat to a Jewish Community Center.

Thompson's page also expresses disdain for President Donald Trump and white people generally. [Emphasis added]
