Counter-terror police are investigating how a small amount of uranium was shipped to the UK on a passenger flight.
The radioactive material was detected in a package at Heathrow Airport following a routine screening on 29 December.
It arrived on a flight from Oman after originating in Pakistan, say Sky sources.
It was found in a shipment of scrap metal.
Counter-terror commander Richard Smith said the amount of contaminated material “was extremely small” and has been assessed by experts as posing no threat to the public.
He added: “Although our investigation remains ongoing, from our enquiries so far, it does not appear to be linked to any direct threat.
“As the public would expect, however, we will continue to follow up on all available lines of enquiry to ensure this is definitely the case.

“However, it does highlight the excellent capability we and our partners have in place to monitor our ports and borders in order to keep the public safe from any potential threats to their safety and security that might be coming into the UK.”
The material has been identified as being contaminated with uranium, the force said, and no arrests have been made.

Former head of the British Army’s chemical weapons unit, Hamish de Bretton-Gordon, told Sky News that it was “a concern” that the material has apparently reached the UK, having come all the way from Pakistan, but that he did not think the public should be overly worried.

He added: “I think it’s excellent that the police and others have interdicted this and made it safe, but we must be on our guard because there are bad people out there who want to do us harm in this particular manner.”
Speculating about the intent, he said that “we must be open to the fact this might be some sort of terror type thing”.
Mr Bretton-Gordon said while there is no indication that a group such as al Qaeda was behind the incident, he argued it “has their trademark and fingerprints on it”.
Whatever the origin, he said the material “absolutely shouldn’t be on a commercial airliner”.
However, defence and security analyst, Professor Michael Clarke, told Sky News he believed it was unlikely to be terror-related.
He said: “It is almost certainly an accident.
“If that was terrorists trying to bring that in, they would be bringing it into the one place in the UK that is bound to catch it.
“Heathrow is the one place where uranium will always be detected – so that almost rules it out.
“The point about uranium is that the Heathrow scanners would immediately pick up any toxic uranium.”

‘Bad people want to do us harm’
The Met said officers are working with partner agencies to investigate the incident and ensure there is no risk to the public.
A Home Office spokesperson said: “We do not comment on live investigations.”
Uranium is a metal that exists naturally in the earth, but is harmful to humans because it is radioactive.
Health Secretary Steve Barclay told Sky News that he hoped for more information in “due course” about the material seized at Heathrow.
He said: “Clearly there is an investigation under way, and it is right that it looks at all the issues, and I’m sure it will report in due course.”
A major incident has been declared in Northern Ireland after a wildfire broke out, the latest in a series of blazes seen across the UK over the past week amid soaring temperatures.
More than 100 firefighters and 14 fire appliances were at the scene of the “significant” wildfire on Sandbank Road, Hilltown, Northern Ireland Fire and Rescue Service said.
The fire had a front of approximately two miles “including a large area of forestry close to property”, the service said.

“Local residents are requested to avoid the area, a number of roads have been closed, to help support firefighting operations,” the fire service added.
“We ask that all members of the public remain particularly vigilant to the risk of fire at this time. We can reassure members of the public that normal service delivery is being maintained.”

Separate incidents were then reported at Upton Heath in Poole on Wednesday, and nearby Canford Heath in the early hours of Thursday.
Friday was officially the warmest day of the year so far – with temperatures in the south of England reaching 23C (73.4F) – the highest since 21 September last year, according to the Met Office.
Labour MP Dan Norris has been arrested on suspicion of rape and child sex offences.
A Labour Party spokesperson said: “Dan Norris MP was immediately suspended by the Labour Party upon being informed of his arrest.
“We cannot comment further while the police investigation is ongoing.”
Police said a man in his 60s had been arrested on Friday on suspicion of sexual offences against a girl, rape, child abduction and misconduct in a public office.
Sky News has contacted Mr Norris for comment.
Mr Norris, 65, defeated Jacob Rees-Mogg to win the new seat of North East Somerset and Hanham in last year’s general election.
He has also lost the party whip in the House of Commons and has stepped down from his role as chair of the League Against Cruel Sports.
Avon and Somerset Police said in a statement: “In December 2024, we received a referral from another police force relating to alleged non-recent child sex offences having been committed against a girl.
“Most of the offences are alleged to have occurred in the 2000s, but we’re also investigating an alleged offence of rape from the 2020s.
“An investigation, led by officers within Operation Bluestone, our dedicated rape and serious sexual assault investigation team, remains ongoing and at an early stage.
“The victim is being supported and given access to any specialist help or support she needs.
“A man, aged in his 60s, was arrested on Friday (April 4) on suspicion of sexual offences against a girl (under the Sexual Offences Act 1956), rape (under the Sexual Offences Act 2003), child abduction and misconduct in a public office. He’s been released on conditional bail for enquiries to continue.
“This is an active and sensitive investigation, so we’d respectfully ask people not to speculate on the circumstances so our enquiries can continue unhindered.”
Mr Norris first entered Parliament when Tony Blair came to power in 1997 and served as the Wansdyke MP until 2010.
He was an assistant whip under Mr Blair and served as a junior minister under Gordon Brown.
Mr Norris has also been West of England mayor since 2021 but is due to step down ahead of May’s local elections.
A spokesman for the League Against Cruel Sports, a UK-based animal welfare charity which campaigns to end sports such as fox hunting and game bird shooting, confirmed he had stepped down from his role.
“The charity cannot comment further while an investigation is ongoing,” a statement said.
Jaguar Land Rover (JLR) has said it will “pause” shipments to the US as the British car firm works to “address the new trading terms” of Donald Trump’s tariffs.
The US president has introduced a 25% levy on all foreign cars imported into the country, which came into force on Thursday.
JLR, one of the country’s biggest carmakers, exported about 38,000 cars to the US in the third quarter of 2024 – almost equal to the amount sold to the UK and the EU combined.
In a statement on Saturday, a spokesperson for the company behind the Jaguar, Land Rover and Range Rover brands said: “The USA is an important market for JLR’s luxury brands.
“As we work to address the new trading terms with our business partners, we are taking some short-term actions including a shipment pause in April, as we develop our mid- to longer-term plans.”
The company released a statement last week before Mr Trump announced a “baseline” 10% tariff on goods from around the world, which kicked in on Saturday morning, on what he called “liberation day”.

JLR reassured customers its business was “resilient” and “accustomed to changing market conditions”.
“Our priorities now are delivering for our clients around the world and addressing these new US trading terms,” the firm said.
Trading across the world has been hit by Mr Trump’s tariff announcement at the White House on Wednesday.
All but one stock on the FTSE 100 fell on Friday – with Rolls-Royce, banks and miners among those to suffer the sharpest losses.
Cars are the top product exported from the UK to the US, with exports worth £8.3bn in the year to the end of September 2024, according to data from the Office for National Statistics.
For UK carmakers, the US is the second largest export market behind the European Union.
Industry groups have previously warned the tariffs will force firms to rethink where they trade, while a report by thinktank the Institute for Public Policy Research said more than 25,000 car manufacturing jobs in the UK could be at risk.
