London: UK Prime Minister Andy Burnham said on Saturday the death of black academic Jason Arday, who resigned from Cambridge University amid a plagiarism scandal that sparked racism claims, was "a tragedy on so many levels".Arday, 41, was found dead on Friday, just over a week after he quit his positions as university professor and Jesus College fellow following both institutions announcing probes into various accusations against him. His family criticised what they called a "campaign of harassment" that followed the allegations about his academic work and personal life, while Arday himself had said that campaign was "racially motivated".
