Tributes have been paid to Jason Arday, the former Cambridge professor, after he was found dead at an address in Battersea, south London, on Friday afternoon.

In a statement issued by his publisher Simon & Schuster UK, Arday’s family said they were “in shock to have lost this amazing father, partner, brother, uncle and son”.

They said a “campaign of misinformation” had been too much for him.

Arday, 41, resigned as a Cambridge professor of sociology of education last week after allegations of plagiarism and questions about some of his achievements. He had denied the claims.

The University of Cambridge vice-chancellor Prof Deborah Prentice led the tributes, saying the faculty was “desperately saddened” to learn of his death.

“Our heartfelt sympathies go to Jason Arday’s family and friends at this incredibly difficult time.”

Education Secretary Lucy Powell said she was “deeply shocked and saddened” to hear about the death and she urged people to “remember there are real people with loved ones involved”.

Mayor of London Sir Sadiq Khan is among those who have said Arday was subjected to unrelenting media scrutiny.

He said Arday had faced “an unacceptable public hounding and campaign of abuse”, adding that he was a victim of “a pernicious public shaming that other people in his position simply wouldn’t have faced”.

“His death was a tragedy, but once again it should be a wake up call for all of us,” he posted on X.

Jo Grady, General secretary of the University and College Union said the “level of harassment he suffered and the racism he was subjected to has been sickening” and “must be investigated”.

Lord Paul Boateng, who became the UK’s first black cabinet minister in 2002 when he was appointed Chief Secretary to the Treasury under Tony Blair, told BBC Newsnight he was ” horrified, shocked and deeply saddened”.

“Racism in academia is a fact of life and needs to be addressed,” he added in a written statement.

In a statement on Saturday, National Education Union (NEU) general secretary Daniel Kebede said Arday had been subjected to “a public and brutal takedown that unleashed a tirade of racism”.

“The effect has been chilling. It tells black people and others from underrepresented backgrounds that entering prominent public positions will make you a target,” he said.

Director of the Autism Research Centre at the University of Cambridge, Prof Simon Baron-Cohen told the Today programme Arday had been “bombarded by every media outlet to paint him as a fraud”.

“He was an incredibly, kind and gentle and caring man,” he said.

He spoke to Arday the morning of his death, and said the academic had felt unable to leave the house.

“He has experienced what he described as a campaign against him, for the last three years,” he previously told BBC News.

“What he was saying to me was ‘they’ve destroyed my life’ – it’s not clear who they were but I think he was referring to the media.”

“The personal attacks on him have been so immense.

“This isn’t to point fingers, and its not a single media outlet, but in the last few weeks since he resigned, I must have received a hundred new requests – to comment on his life.”

Speaking to BBC Newsnight, Professor of Black Studies Kehinde Andrews, a friend of Arday, described him as “very down” after resigning from Cambridge.

“He was very upset. He felt that there was no way out. He effectively wasn’t leaving the house. He had lost a lost of weight,” Andrews said.

“There should be a wakeup call to just how bad black academics actually have it in academia.”

Labour MP Bell Ribeiro-Addy also told the programme “the idea that an academic would be dragged through this amount of media scrutiny is unheard of”.

Shadow communities secretary Sir James Cleverly said he was angered by the “tragic” death and said “a number of people at a number of academic institutions have serious questions to answer”.

“His whole world fell apart,” he said in a post on X.

Arday had denied any plagiarism – but admitted errors in his work – and said the recent controversy about his work had led to “an unrelenting level of public scrutiny and personal attack”.

The row first erupted after another academic – self-defined “race realist” Nathan Cofnas, who was sacked from his Cambridge role in 2024 – said he found numerous instances of plagiarism in the professor’s work.

Arday said some errors in his early academic work arose because of his autism, as he relied on using mimicry to make sense of information. Similar scrutiny would find similar errors in work by other academics, he said.

Questions were also raised about parts of his life story, including that he ran 600 miles in six days and that he had raised £5.5m for charity.

He later said the run was actually completed over a 12-day period to allow for rest days – and that the huge sum was raised with the help of others.

Arday’s appointment as Cambridge’s youngest ever black professor at the age of 37 in 2023 was hailed at the time as a progressive moment.

Announcing his resignation last week, Arday said the “personal cost” of the scrutiny of him had become “too great”.

He said: “While criticism is an inevitable part of academic life, what I have experienced has gone far beyond scholarly disagreement.

“The relentless accusations, speculation and public commentary have taken a profound toll on me and on those I love.”

He stressed that his resignation should not “be mistaken for an acceptance of the narratives that have surrounded me”.

Earlier this week, Cambridge announced it would be launching an independent investigation around the circumstances of Arday’s appointment.

It had initially said claims of plagiarism regarding Arday’s thesis and some journal publications had been investigated by Liverpool John Moores University (LJMU) and the journals in question.

LJMU – which awarded Arday his PhD in 2015 – concluded that he had not plagiarised work.

In a statement on Saturday, a spokesperson for the university said it was “saddened to hear of the tragic loss of Professor Jason Arday”.

“At this time our thoughts are with his family and friends, and the many colleagues and students who will be feeling his sudden loss so acutely,” they added.
