"Norfolk police close case and confirm the hack came from 'sophisticated' outsiders – not a University of East Anglia leak."
"Norfolk police on Wednesday formally closed the two-and-a-half-year investigation into the hacking of emails from the University of East Anglia's (UEA) Climatic Research Unit (CRU), and confirmed the hack was the work of "sophisticated" outsiders, not a whistleblower at the university.
The breach – dubbed "climategate" - led to thousands of private emails exchanged between climate scientists over the previous decade being dumped online in November 2009. A second tranche of emails was uploaded onto the internet late last year.
The incident led to numerous inquiries into the practices of the scientists, all of which cleared the scientists of wrongdoing. The university, however, was criticised for its data handling and response to freedom of information requests.
Detective chief superintendent Julian Gregory, the senior investigating officer, said: "Despite detailed and comprehensive inquiries, supported by experts in this field, the complex nature of this investigation means that we do not have a realistic prospect of identifying the offender or offenders and launching criminal proceedings within the time constraints imposed by law. The international dimension of investigating the world wide web especially has proved extremely challenging.""
