A vile paedophile who made 3D prints of genitals and owned more than 100,000 child abuse images has been jailed.

A public protection officer found out convicted sex offender, Paul Rapson, was buying children's underwear online after snaps showed he wore them in selfies.

The 49-year-old from Batley, Yorkshire, was already subject to a lifelong sexual harm prevention order following his prison sentence in 2009 for 22 sexual offences, Examiner Live reports.

Rapson was released from prison in 2011 but remained on the sex offenders register having abused a young boy, taken indecent photos of children in public and having indecent images.

The public protection officer visited Rapson's parents' home in Kirkheaton in 2017 as they had become aware that he had taken photos of himself wearing children's underwear that he had bought online.

Rapson avoided arrest by claiming he only used his parents' internet to use eBay and look for a job, the court heard.

But the authorities later became aware that Rapson spent a "considerable" amount of time at his parents' house where he kept computers and a camcorder, which were seized on June 18 2018.

The devices were seized on August 22, 2017 and found to contain 47 indecent images in the most serious category and 87 in category B and 3,271 in category C.

Rapson made prints of genitals at home using a 3D printer

Prosecutor Andrew Semple said one of the images was of a 14-year-old boy tied to a chair and being abused.

Rapson's search history included the terms "Lolita", "paedophile" and "virgin" and more than 100,000 other images on the devices were not analysed.

A card reader, phones and a 3D printer were found at his home on Cardigan Close, Batley on the same date, although no indecent images of child abuse were found on those.

The printer had been used to print out models of vaginas and a penis.

In a box, he had children's underwear along with photos of children's underwear.

The sicko was handed an eight-year extended sentence at Leeds Crown Court on Monday for his latest offences. Of that time, three years must be served behind bars, followed by a five-year extended licence period.
