Haverford Professor Arrested for Antisemitic Threats

A Haverford College professor was arrested Tuesday after cyberstalking and sending antisemitic threats to a colleague, The Philadelphia Inquirer reported. 

Guangtian Ha, an assistant professor of religion at Haverford, sent more than 50 threatening messages to his colleague between October 2025 and May of this year, when his anonymous X accounts were suspended, according to court documents. The messages invoked the Holocaust, Adolf Hitler and Hamas’s Oct. 7, 2023, terrorist attack on Israel. 

In one message Ha wrote, “The end of American jews is close. Let’s start with the jews in Lower Merion,” the Philadelphia township where Haverford is located. In another he said, “If jews are so special then they should also be placed in special camps and receive special treatments,” court documents show. 

Ha also posted identifying information about his colleague online, including their home address and their infant child’s name, and posted photos of the family’s mailbox. 

The FBI linked the anonymous accounts to Ha via his IP address. He was charged with online harassment and intimidation and faces up to five years in prison, three years of supervised release and fines, the Inquirer reported.

“I am heartbroken and furious at the possibility that an individual within our community would seek to inflict such pain on another,” Haverford President Wendy Raymond said in a statement Tuesday. “This disturbing news is made even more harmful for many given its proximity to both the Jewish High Holidays and the third anniversary of the October 7 attacks.”

Haverford placed Ha on administrative leave and barred him from campus while the criminal investigation is ongoing. He had been on sabbatical leave and was not teaching this academic year, Raymond said. 

In a statement Wednesday, Anti-Defamation League Philadelphia senior regional director Andrew Goretsky said the organization was “grateful” for Haverford’s quick response.

“Antisemitic harassment and threats must never be tolerated,” Goretsky wrote. “These are allegations, and the defendant is entitled to the presumption of innocence. But if they are proven, we must ask: How could someone like this be entrusted with teaching our students?”
