Video: Oxford professor's death 'a sad day for everyone' An Oxford University don with whom Professor Rawlings co-authored a book was held on suspicion of his murder but has since been released on police bail. Devinder Sivia was arrested on Wednesday night at his home in Southmoor, Oxford, after police discovered the body of Professor Rawlings there. After Dr Sivia left Abingdon police station, police said the death may be "a matter for a coroner's inquest rather than a criminal court." Emergency crews were called to the suburban home at 1122pm on Wednesday to reports that a man had been injured. Paramedics attended but the married Professor, 50, was declared dead at the scene. A post-mortem examination carried out on Thursday was unable to establish a cause of death and further tests will be conducted. Professor Rawlings and Dr Sivia were said to be firm friends and published a book together in 1999 called Foundations Of Science Mathematics. Dr Sivia, of St John's College, has taught maths for natural sciences to chemistry and physics undergraduates for a number of years. Tributes were paid to Dr Rawling, a St Peter's College academic. Vice-chancellor of Oxford University Professor Andrew Hamilton said in a statement: "The entire university community has been profoundly saddened and shocked by the tragic and untimely death of Professor Steve Rawlings.
