Uranium in cargo caused alert at Heathrow Airport
A small amount of uranium was detected in a package that arrived in the UK at Heathrow Airport following a routine screening.
The Metropolitan Police said its counter-terrorism command unit was contacted by Border Force colleagues at the airport after the contaminated material was discovered on 29 December.
It was found in a shipment of scrap metal, a source said, and came from Pakistan.
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.
The package was destined for Iranian nationals in the UK and arrived on a flight from Oman after originating in Pakistan, according to The Sun.
The shipment's intended destination is not clear. No-one has been arrested.
