Thomas Gwilliam-Carter, 39, shared videos with other paedophiles of a child under the age of 13 that he had drugged and raped. He was also found to be in possession of thousands of indecent images of children and even babies.
The 39-year-old electrician was identified after abuse images he posted online were discovered on devices belonging to another suspected paedophile in the United States that was later arrested by the FBI, the National Crime Agency confirmed.
Online chat logs found by authorities showed Gwilliam-Carter, hiding behind an online pseudonym, announcing to other abusers that he was planning to sexually assault a child after drugging them.
Gwilliam-Carter, of Caswell Road in Leominster, Herefordshire, recorded the sickening attack and later shared the footage online.
Officers raided his home on October 1, when they seized his phone, they discovered 3,651 indecent images of children and babies, many in the most serious criminal category.
On November 7, at Worcester Crown Court, Gwilliam-Carter pleaded guilty to one count of rape of a child under 13, three charges of making indecent images of children, and five counts of distributing illegal images.
Today, December 8, he was jailed for 15 years and nine months - he was also ordered to sign the sex offenders register for life.
National Crime Agency operations manager Phil Eccles said: "Gwilliam-Carter inflicted the most terrible abuse on a young girl and distributed videos he had made of it online, all for his and other paedophiles' pleasure.
"Child sexual abuse is a global threat and this case highlights why the NCA's close co-operation with international partners is so vital in tackling it.
"We also work tirelessly to protect those affected by child sexual abuse and disrupt offenders who pose a sexual threat to children, ensuring they face justice."
