A murder investigation has been launched into the death of 42-year-old Adrian Greenwood, who was found dead in the hallway of his home in East Oxford on Thursday.

Police were called to his three-storey property on Iffley Road at 3pm, after a cleaner found a man inside the hallway.

A post-mortem yesterday confirmed the cause of death as multiple stab wounds to the chest and neck.

Thames Valley Police believe these wounds were inflicted with a bladed object, but they are yet to recover a murder weapon.

They also believe that an altercation took place in the hallway of the house and that Mr. Greenwood died after a “vicious and sustained attack,” in which the offender may also have obtained injuries.

A 26-year-old man has been arrested on suspicion of murder and is currently in custody.

An onlooker, who saw the arrest yesterday, told Cherwell, “I was walking up the high street at around 18:15 when I saw a small grey car barreling through the high speed with the car horn blaring, closely followed by a police car. Both cars were coming from Cowley. I walked past Quod a few minutes later and saw the two cars parked in the middle of the road. Two policemen, one plain-clothed, were speaking to a man who had a couple of bloody cuts across his cheek.”

Detective superintendent Chris Ward, head of Thames Valley Police major crime unit, commented, “We are keeping an open mind in terms of the motive and whilst we have already made an arrest in connection with this investigation, I anticipate further arrests will be made as the investigation continues.”

Mr. Greenwood read Philosophy, Politics and Economics at Christ Church before embarking on a career as an antiques dealer, according to his website.

On the same site he described himself as a “historian, biographer, author and art dealer with a particular interest in nineteenth century British military history”.

He retired four years ago to focus on his writing, producing hundreds of articles since about antiques.

A blue tent was erected outside the house, whilst Forensic teams searched through bins, hedges and drains along the street.

Hugo Kent-Egan, an Oxford student who lives nearby, commented, “I remember seeing the police tape closing off the section of Iffley Road when I was cycling into college yesterday and wondering what was going on, only saw the story just a few hours ago.

“Obviously there are very few details about the incident such as motive and so on, but it was really shocking to read the article and recognise the picture of his house on Iffley Road, just a 5 minute walk from where we live. For something like that to happen virtually on our doorsteps seems very surreal and out of place.

“Considering that to most people Oxford seems a very safe and fun place to live and that the only crime I’ve really ever come across this year in Cowley are bicycle thefts or burglaries, something like this really jars with people sense of safety and will perhaps make me more wary this term.”

Iffley Road reopened last night after officers were seen removing grey Vauxhall Vectra from the property.

However the three-storey house and three nearby properties remained cordoned off this morning.

A spokesman said Mr. Greenwood’s next of kin had been informed, although he is yet to be formally identified.

UPDATE (April 10 2016): Man arrested by police on the High Street released without charge by police.

Oxford University told Cherwell Wednesday morning that mentions of Oscar-winning director Pedro Almodóvar, and his brother Agustín, in the Panama Papers have had “no impact” on the plan to award the Spanish filmmaker with an honorary degree. Almodóvar has, however, cancelled media events related to his new film, Julieta.

The decision to award Almodóvar was announced February 22, with the University at the time explaining that “Mr Pedro Almodóvar is a director and screenwriter, winner of the Jean Renoir Award for Screenwriting Achievement, and Foreign Honorary Member of the American Academy of Arts and Sciences. He achieved international recognition for the film Women on the Verge of a Nervous Breakdown in 1988, and has since won multiple awards for Talk to Her, All About My Mother, and Volver, among others.”

“In any case, I reiterate that both my brother Pedro and I, as well as our producer, are up-to-date with all of our tax obligations.” – Agustín Almodóvar

It was revealed earlier this week by the Panama Papers that the Almodóvars were complicit in using tax havens to hide their wealth offshores, away from taxation. While being named in the Panama Papers does not necessarily amount to evidence of criminal wrongdoing, Iceland’s prime minister has already been forced to resign after appearing in them and dozens of other prominent figures have been implicated in the 11.5 million document leak.

Agustín Almodóvar took responsibility for his brother, saying that from the beginning, “Pedro and I divided up the tasks and duties very clearly. I took charge of all of the issues related to the management of the company, and he dedicated himself to all of the creative aspects.”

“In this context, I would like to clarify that the creation of the company in 1991 was on the recommendation of my advisors given a possible international expansion of our company. Notwithstanding that, the company was left to die without activity because it did not fit in our way of working.”

Energy companies can only go on building new coal and gas power stations for one more year if the world is to meet its global warming targets, according to a new study by Oxford academics.

Researchers at the Institute of New Economic Thinking have shown that the electricity generating infrastructure likely to give 2°C warming will have been reached by 2017. After the ‘2°C capital stock’ is exhausted, all new electricity sector investments will need net zero emissions in order not to exceed the internationally agreed global warming target.

At the Paris Climate Agreement in 2015, representatives from 195 countries agreed to “holding the increase in the global average temperature to well below 2°C above pre-industrial levels”.

This Oxford study casts serious doubt, however, on whether this is achievable. Stressing the urgency of the situation, the paper states that “the energy system is now at risk of undermining climate stability.”

When asked about the relative importance of the energy sector in achieving the climate goals, Richard Millar, one of the authors of the paper, told Cherwell, “Energy and heat currently contributes about four per cent of global carbon dioxide emissions.” He added, “carbon dioxide-induced warming of the climate system is essentially permanent.”

If policymakers ignore the findings of the study, they run the future risk of “stranding otherwise economically valuable assets,” which would “likely induce significant costs and loss of capital”.

The study defines ‘2°C capital stock’ as infrastructure that gives a 50 per cent chance of 2°C warming based on the normal economic lifespan of power plants, and with the optimistic assumption that all other sectors reduce emissions in line with the Paris Agreement struck in December.

Harriet Waters, Head of Environmental Sustainability at Oxford University, told Cherwellthat “the University is currently spending in the region of £1.5-2 million per annum on energy saving projects,” adding, “99 per cent of the University’s purchased electricity comes from a renewable source.”

The idea that no new carbon dioxide emitting infrastructure can be built in less than two years’ time has serious implications for the investment in the energy sector. Perhaps as a sign of the sector’s uncertain future, a spokesperson for the Oxford University Endowment Fund, responsible for £2 billion of assets from university colleges, told Cherwell, “we have already have significantly lower exposure to energy than if the fund was passively invested.”

Oxford’s Theology degree will no longer contain an obligatory Christianity component past first year as of Michaelmas 2016. While Theology prelims will retain two compulsory Christianity modules, Theology FHS will not. The same applies to Theology and Oriental studies as well as Philosophy and Theology. The Theology course itself has also been renamed Theology and Religion.

Johannes Zachhuber, Board Chairman of the Theology Faculty and Professor at Trinity College, told Cherwell that this was a result of “a five-year review process involving both academics and students.”

He attributed the change to the wishes of both undergraduates and academics, saying, “We recognise that the people who come to study at Oxford come from a variety of different backgrounds and have legitimately different interests. They come from the respected communities of Britain.

“If you have a very rigid curriculum, there will be an increasing mismatch between what lecturers are doing in their research time and what they’re having to teach.”

Zachhuver said that the course will now include “a wide variety of papers covering Christianity, Islam, Judaism, Buddhism, and Hinduism as well as many different methodological approaches to the study of religion including theological, historical, sociological, and anthropological ones.”

He hopes it will also allow students to “critically [question] Western assumptions about religion which often imply the inferiority of non-Western cultures.”

Dr Benjamin Thompson, Coordinator of Undergraduate History, told Times Higher Education that this fell into a broader pattern, saying, “With the Cecil Rhodes statue debate, this ‘decolonisation’ of the curriculum is now quite interesting.”

Harry Cain, a third year Philosophy and Theology student, was enthusiastic about the proposal. He told Cherwell, “If the Christianity papers weren’t compulsory, I potentially would have looked into an area of theology like Islam or Buddhism to see how the worldviews interlink and draw on each other; with this change, hopefully students like myself will pursue their interests more rather than learning modules which are taken solely out of necessity for the course.”

However, he highlighted a fear that the course might risk “becoming an assortment of distinct topics rather than separate insights into an overarching worldview.”

Oxford’s Christian Union (OICCU) replied to Cherwell’s request for comment by stating that it was not the place of the society to comment on decisions made by the Theology Faculty.

The Oxford Islamic Society has been contacted for comment.
