The University of Cambridge has announced an investigation into its professor Jason Arday following what it called "new information" regarding his qualifications and career. This was reported by infohub.kz.

Initially, Cambridge defended Arday – the youngest black professor appointed in the university's history, with a compelling life story of educational disadvantage – as "the victim of a vile campaign". However, as questions mounted over Arday's own claims, the university's leaders felt that Cambridge's reputation was in danger.

The Guardian published its own investigation uncovering discrepancies in Arday's public accounts involving prodigious fundraising feats as well as claims he had been targeted by knife-wielding masked intruders.

Arday first faced allegations that he plagiarised his PhD thesis and some of his published academic research late last year, and has denied the claims. An investigation by Liverpool John Moores University, which awarded his PhD in 2015, did not uphold the charges of plagiarism but said they were probably caused by "honest and reasonable error".

Arday has denied plagiarism, and told The Times: "I am accountable for the mistakes I've made. I hold myself accountable and other people should hold me accountable. We're talking about academia here. I didn't murder somebody. I think the cruelty that I've experienced, and the positioning of me as this kind of liar and fantasist, is totally unacceptable."

A statement published on Wednesday evening said: "The University of Cambridge has begun an investigation following new information about Prof Arday's academic qualifications and honorary appointments. In order to ensure a fair process, we will not comment further until this has concluded.

Separately, there remains a number of ongoing complaints regarding academic misconduct, which are being handled in line with our misconduct in research policy. This is consistent with our previous statement on the matter.

While we are fully aware of the public commentary and concerns around this matter, it remains vital that any process is thorough and adheres to both university policies and employment law.

We also fully recognise that there is a person at the centre of this situation, and we continue to provide support to him."
