Nathan Cofnas, a former Cambridge scholar, claimed on social media platform X that he fears for his life after attending an anti-Cofnas hate rally disguised as a vigil at Trafalgar Square in London, which drew an estimated 30,000 people. Cofnas had previously exposed plagiarism allegations against Jason Arday, a 41-year-old former Cambridge professor who resigned amid similar claims. The controversy surrounding Arday's academic career has led to multiple investigations and reviews of his work, with some finding significant similarities between passages in his thesis and earlier academic material. Cofnas claimed that the crowd at the vigil made him believe there was a real possibility he could have been murdered if he had been present.

Story summary
Jason Arday, a 41-year-old professor at the University of Cambridge who was its youngest Black professor when appointed in 2023, has been found dead after resigning amid allegations of plagiarism and media scrutiny. The allegations, which included similarities between passages in his PhD thesis and earlier academic work, were first made by Nathan Cofnas, a philosopher of biology at Ghent University. Cofnas had published a detailed analysis on his Substack newsletter, claiming that large portions of Arday's thesis contained material closely matching or identical to earlier work by other scholars.
The allegations led to a media storm, with many outlets reporting on the plagiarism claims and Arday's resignation. However, Arday's family disputed the allegations, saying that he was subjected to a "campaign of misinformation" and had been "subjected to a campaign of sustained abuse" by those who would "leave no stone unturned in their quest to undermine him."
In response to the scandal, Cambridge announced an investigation into Arday's qualifications, honorary appointments, and academic misconduct complaints. Ghent University also launched a preliminary disciplinary investigation against Cofnas, suspending him as a precautionary measure.
The controversy surrounding Arday's death has led to questions about racism and media pressure, with some blaming a "racist feeding frenzy" prompted by the plagiarism claims. The University of Cambridge's chancellor has condemned the situation, saying that it was right to refuse to join in a racist feeding frenzy over a particular academic.
