Federal authorities have arrested a disgraced former journalist from St. Louis for making a number of threats against Jewish institutions as part of a vicious internet campaign against a former lover.

Juan Thompson, 31, was arrested by the FBI in St. Louis on Thursday for allegedly making bomb threats against at least eight Jewish community centers, the US Attorney's Office said.

Thompson is alleged to have engaged in ‘a campaign to harass and intimidate', prosecutors said.

Thompson is a former journalist who was fired from The Intercept after it was learned he had fabricated quotes and invented sources.

The news site, which focuses on national security issues, acknowledged last year that Thompson used fake email accounts to impersonate others.

He was also found to have attributed quotes to individuals in news stories even though those people later said they were never interviewed.

Thompson was charged in New York with cyberstalking a woman by ‘communicating threats to JCCs in the woman’s name.’

If convicted, Thompson faces up to five years in federal prison. He is due in a St. Louis federal court on Friday.

Thompson ‘appears to have made at least eight of the JCC threats as part of a sustained campaign to harass and intimidate’ the woman after their romance ended.

Approximately 100 Jewish centers have been threatened in recent weeks. In addition, Jewish cemeteries have been vandalized and headstones knocked over.

Thompson will also be questioned about the tombstone desecrations, authorities said.

On Monday, 21 bomb threats were phoned in to 13 JCCs and eight Jewish schools in Alabama, Delaware, Florida, Indiana, Maryland, Michigan, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island and Virginia.

Thompson is also alleged to have sent 'defamatory emails and faxes' to the woman's employer as well as 'false reports of criminal activity' by the woman.

Federal authorities allege that Thompson had falsely claimed that the woman possess child pornography back in October.

When questioned about the claim in November, Thompson told investigators that his internet was hacked.

The government alleges that Thompson began to make threats against Jewish institutions back in January.

On or about February 21, Thompson allegedly emailed a threat to the New York offices of the Anti-Defamation League.

'[The woman] is behind the bomb threats against jews,' the email read. 'She lives in nyc and is making more bomb threats tomorrow.'

The next day, the ADL received a phone call stating that explosive materials had been placed in its midtown Manhattan office.

The federal government also alleges that on or around February 7, a JCC in Manhattan received an emailed bomb threat from an anonymous account.

'Juan Thompson put two bombs in the office of the Jewish center today,' the email read. 'He wants to create Jewish newtown tomorrow.'

'Newtown' is a reference to Newtown, Connecticut, the site of a December 2012 school shooting that left 26 people dead, among them 20 children.

Federal authorities also say that Thompson used his Twitter feed to allege that the woman in question made threats against him as well as President Donald Trump.

Thompson claimed in the tweets that the woman was trying to frame him.

'Y'all know how to get a social worker in NY barred?' he tweeted on Monday. 'I'm being stalked and harassed by a white nasty white woman in NYC.'

He tweeted that he had been questioned by the FBI and the Secret Service who were investigating the matter.

'The Secret Service visited me looked at my tweets, questioned my politics b/c some awful white woman I date reported me,' Thompson tweeted the same day.

'I won't be silenced.'

The ADL tweeted on Friday that the suspect behind the threat had been arrested

In a pinned tweet on his account, he wrote a rambling note filled with accusations against the woman and 'the racist FBI.'

‘Two years ago, after swearing off white women, I started dating one,’ he tweeted.

‘She seemed like a cool Brooklyn white radical. There were [sic] warning signs though; she didn’t tell me she had herpes until AFTER we hooked up; she called me a thug, in an approving way, because she liked I was wearing Js and balling shorts after the gym; and she called herself captain save-a-thug – a reference to the type of black men she dated.’

‘We broke up after someone showed me the light, and since then she’s stalked and harassed me,’ he wrote. ‘[She] threatened to have me killed, and said she was going to make me a prison ‘statistic’ and looked forward to me being ‘raped’ in prison.’

‘[The woman] is a clinical [sic] director at a prominent NYC non-profit.’

‘She, though I can’t prove it, even sent a bomb threat in my name to a Jewish center, which was odd given her anti-Semitic statements.’

‘I got a visit from the FBI. So now I’m battling the racist FBI and this vile, evil, racist white woman.’

‘I’m afraid…we know what happens when white women use the law to go after black men.’

On Sunday, Thompson re-tweeted a number of news stories about the bomb threats against the JCC as well as other historical articles and references to anti-Semitism and the Nazis.

'The hatred of Jews goes across all demos,' he tweeted in a post that was referenced in the US Attorney's Office complaint.

'Ask NYC’s [employer of the woman in question,' he tweeted. 'They employ a filthy anti-Semite. These ppl are evil.'

'Thompson’s alleged pattern of harassment not only involved the defamation of his female victim, but his threats intimidated an entire community,' FBI Assistant Director-in-Charge William Sweeney said.

'The FBI and our partners take these crimes seriously.'

After Thompson's arrest, Jewish community leaders met with FBI Director James Comey.

The JCC Association of North America said Friday's meeting included discussion of threats directed against Jewish institutions in the past two months.

The association says the Jewish community is deeply grateful for the FBI's 'extraordinary effort.'

It says representatives left the meeting 'with the highest confidence' that the agency will work to resolve the matter soon.
