An investigation into allegations that Sheffield Hallam University faced sustained pressure from China to shut down human rights research has been referred to counter-terrorism police.

The BBC and the Guardian newspaper has been reporting that documents show that China had waged a two-year campaign of intimidation and harassment, including demands the university stop sensitive research by one of its professors into claims of forced labour in the Xinjiang region of China.

A South Yorkshire Police spokesperson said the force has referred the investigation on because the “allegations fall under Section 3 of the National Security Act”.

Section 3 of the act deals with “assisting a foreign intelligence service”.

An offence is committed if someone behaves in a way that “intends that conduct to materially assist a foreign intelligence service in carrying out UK-related activities,” or in conduct likely to assist that service.

Internal documents from Sheffield Hallam University were released under a Subject Access Request to Professor Laura Murphy, whose research is alleged to have been targeted.

They showed university staff in China had been threatened by individuals identified as being from China’s National Security Service, who demanded the research by Prof Murphy taking place in Sheffield be shut down.

The documents went on to state that “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”.

China is not believed to have an organisation named National Security Service, so it is not clear who the individuals were.

The decision referred to in the documents is alleged to have led to Prof Murphy being told by the university that she could not continue her work on China at the start of this year – then reversing that position after she started legal action for infringement of her academic freedom.

In a statement issued earlier Sheffield Hallam University had apologised to Prof Murphy.

A spokesperson said: “The University’s decision to not continue with Professor Laura Murphy’s research was taken based on our understanding of a complex set of circumstances at the time, including being unable to secure the necessary professional indemnity insurance.”

The insurance for social sciences staff had been suspended by the university’s insurers as a Chinese firm had brought a defamation suit against Sheffield Hallam after it was named in a report she produced. That lawsuit is ongoing.

The university spokesperson added: “Following a review, we have since approved Professor Murphy’s latest research and are committed to supporting her to undertake and disseminate this important work.

“For the avoidance of doubt, the decision was not based on commercial interests in China.

“Regardless, China is not a significant international student market for the University.

“We have apologised to Professor Murphy and wish to make clear our commitment to supporting her research and to securing and promoting freedom of speech and academic freedom within the law.”

US President Donald Trump’s administration has said it will provide reduced food aid to more than 42 million Americans, as the government shutdown this week heads towards becoming the longest ever with no resolution in sight.

The US Department of Agriculture (USDA) said in a court filing that Americans who receive food assistance will get half their normal monthly allotment, after the government dipped into emergency funding.

Judges had given the Trump administration until Monday to provide a plan for how it would pay out Supplemental Nutrition Assistance Program (Snap) benefits, also known as food stamps.

Funding for the programme has been in limbo due to the more-than-month-long shutdown.

While individual US states administer the benefits, the programme relies on money from the federal government, which has been unfunded and shut down since 1 October.

States will get clarity on how they are to distribute the reduced funds by the end of the day on Monday.

Federal judges in Massachusetts and Rhode Island ruled that the USDA needs to use $5.25bn (£4bn) in emergency funds to make at least partial payments to Americans on Snap.

Snap costs about $8bn per month.

The judges both said the Trump administration could use the money set aside for contingencies to provide the benefits.

President Trump previously said he had instructed government lawyers to ask the courts how the administration could legally fund Snap, adding: “Even if we get immediate guidance, it will unfortunately be delayed.”

On Sunday, Treasury Secretary Scott Bessent said in a CNN interview that the president wanted to hear from the courts about how to legally move money around to fund Snap payments, but they could go out as soon as Wednesday.

“There’s a process that has to be followed,” Bessent said. “So, we’ve got to figure out what the process is.”

Late last month, the USDA said it would not distribute food-assistance funds starting 01 November because of the shutdown, saying: “The well has run dry.”

Half the states and the District of Columbia sued the administration over the food-aid freeze and argued that they had a legal obligation to keep the programme running in their jurisdictions.

Separately, cities and non-profits also filed a lawsuit. Some states said they would use their own money to fund Snap benefits.

Snap allows many low-income Americans to buy groceries. It provides them reloadable debit cards that they can use to buy food.

A family of four on average receives $715 per month, which breaks down to a little less than $6 per day, per person.

Diane Ladd, three-time Academy Award nominee and star of Wild at Heart, has died at 89.

Her daughter, actress Laura Dern, confirmed her death on Monday.

“My amazing hero and my profound gift of a mother, Diane Ladd, passed with me beside her this morning,” Dern said in a statement, adding that her final moments were spent at home in California.

Dern, who starred with her mother in 1991’s Rambling Rose, did not share Ladd’s cause of death.

“She was the greatest daughter, mother, grandmother, actress, artist and empathetic spirit that only dreams could have seemingly created,” Dern said. “We were blessed to have her.”

Ladd’s career on stage and screen spanned decades. Her big break in film came in a waitress role in Martin Scorsese’s Alice Doesn’t Live Here Anymore in 1974, which earned her an Oscar nomination.

She went on to appear in dozens of films after that including as recently as 2022, when she played a grandmother in the coming-of-age film Gigi & Nate, and also acted frequently on television shows.

She was married to actor Bruce Dern from 1960 to 1969.
