Haverford Professor Charged with Federal Cyberstalking Over Alleged Antisemitic Threats
Guangtian Ha arrested for allegedly sending dozens of threatening messages to a Jewish colleague, prompting college to bar him from campus.
Haverford College professor Guangtian Ha was arrested Tuesday and charged with federal cyberstalking for allegedly sending numerous antisemitic threats to a Jewish colleague. The college has barred Ha from campus following the charges.
Haverford College President Wendy Raymond stated in a message to the community that she was "heartbroken and furious" about the allegations. "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," Raymond said.
According to a federal indictment, Ha allegedly used at least four anonymous X accounts to send approximately 50 threatening messages to a colleague between October 2025 and May 2026. Prosecutors claim Ha posted the colleague's home address, referenced the colleague's children, and made statements invoking the Holocaust. The colleague's spouse and three children reportedly left their home twice due to the threats.
The arrest follows previous allegations against Ha that were part of a 2024 antisemitism lawsuit filed against Haverford College. In that lawsuit, Jewish students accused Ha of posting hostile social media messages about supporters of Israel, including a statement where he allegedly said he knew their identities and would "never forgive them."
The lawsuit alleged that Ha's remarks were threatening and that college administrators were aware of his posts by September 2024, but had taken no effective action. While the previous lawsuit did not establish unlawful conduct by Ha, the allegations are separate from the federal cyberstalking charge.
Ha, who was on sabbatical and not teaching this academic year, has been placed on administrative leave pending the outcome of the criminal proceedings. "Any form of harassment or discrimination based on identity is unacceptable, antithetical to our values, and has no place at Haverford," Raymond stated.
Raymond also expressed gratitude to federal and local authorities, including the FBI, Haverford Township Police Department, and Campus Safety, for their assistance in the investigation.
Haverford College settled a separate lawsuit in August brought by Jewish students who alleged the college failed to adequately address antisemitic harassment following the Oct. 7, 2023, attacks in Israel. As part of that settlement, the college committed to annual antisemitism awareness training, policy revisions, and the creation of a committee to address antisemitism. A federal judge had previously dismissed a Title VI discrimination claim in that case but allowed a breach-of-contract claim to proceed.
