A maths student at one of London’s most prestigious universities has been jailed for downloading and sharing some of the worst child abuse images ever discovered by police.
Officers said Nur Nordin's collection of more than 30,000 indecent images of children included some of the "most extreme" material they have ever come across.
Police found a life-size mannequin of a young boy when they raided the 23-year-old's home in Queensborough Terrace, Bayswater, last November, after tracing his internet account.
The Malaysian student won a scholarship to study maths at Imperial College and moved to London in 2014.
DC Sara Keane, of the Met’s Serious Crime Unit, said: "Nordin was involved in the making and sharing of some of the most extreme images that have ever been seen by officers that work in this field.
"The volume of images and the alarming content meant that a custodial sentence for Nordin was inevitable."
Among the thousands of images on his laptop and other electronic devices were a "significant" number of the highest category, meaning they depicted the most extreme abuse, police said.
Nordin was today jailed for five years at Southwark Crown Court for a total of 13 offences, including possession of indecent images and videos of children, and intent to distribute the material.
He will be considered for automatic deportation when released.
DC Sara Keane added: "This appalling case demonstrates the danger some adults pose to young and vulnerable children.
"Those who download this material, and then distribute to others, are fuelling the demand and creating yet more defenceless victims."
