"Things in Beijing have kicked off," an internal email from 18 April 2024 said.
The risk summary detailed that "three officers of the National Security Service" visited Sheffield Hallam's office in China.
A local staff member was "questioned for two hours regarding the HKC research and future publications.
"The tone was threatening and message to cease the research activity was made clear."
At another visit, security officers said the internet issues were because the Uyghur research was available on the university website.
Finally, in September 2024, the document states "a decision by the university not to publish a final phase of the research on forced labour in China was communicated to the National Security Service .. immediately relations improved and the threat to staff wellbeing appears to be removed".
Sheffield Hallam says these internal communications need to be seen in context and do not represent university policy.
Complicating things for Sheffield Hallam had been a report by its Forced Labour Lab published December 2023 into clothing supply chains connected to Xinjiang.
Smart Shirts Ltd, a Hong Kong supplier of garments with customers in the UK, brought a claim for libel, alleging it had been defamed as its name was included.
A preliminary ruling at the High Court in London in December 2024 found that report had been "defamatory".
A full trial in that case is yet to take place at which Sheffield Hallam will be able to put forward its defence to the company's claim, but the university was told by its insurers that "any defamation, libel or slander" claims linked to its entire Social and Economic Research Institute were no longer covered.
Professor Murphy had, meanwhile, built an international profile.
