Darren Welsby, 48, has been jailed for 23 years after being convicted of rape and sexual abuse of six children, following a landmark forensic investigation that linked abuse images to his device.
Welsby abused the children between 2012 and 2020, and distributed videos of his abuse on dark web forums. He was caught after Australian investigators uploaded footage to an INTERPOL database, and officers identified him through images of his hands and pictures he had shared on an adult pornography site.
Arrest and Evidence
Welsby was arrested by National Crime Agency (NCA) officers at Manchester Airport in August 2020, when his phone was seized. A search of his former home in Wythenshawe uncovered 58 exhibits, including 10 digital devices containing more than 30,000 indecent images of children, some dating back to 2005.
Among the material were photographs and videos taken by Welsby himself, capturing his sexual abuse of children, including rape and sexual assault. Investigators found 4,700 category A images, the most serious classification, alongside 4,500 category B images, 24,000 category C images and 18 extreme pornographic images depicting bestiality.
Court Proceedings
Manchester Crown Court heard how Welsby abused six children between 2012 and 2020. He also secretly took indecent photographs of his victims and caused some to engage in sexual activity, recording his offending.
He was jailed on Tuesday (October 20), after being convicted of all 18 offences following a two-week trial. The jury returned its verdicts on July 10. His convictions included rape of a girl under 13, sexual assault of a girl under 13, causing or inciting a girl under 13 to engage in sexual activity, offences involving indecent images of children and possession of extreme pornographic images. He will also serve an extended licence period of five years.
Dark Web Investigation Exposed Welsby
An NCA investigation began in 2020 after officers examined three sets of child sexual abuse images uploaded to an INTERPOL database used by law enforcement agencies around the world to identify victims and perpetrators. The images had been uploaded to the dark web using The Onion Router, known as TOR, under the username “wellhnug”. Investigators working for the Australian Federal Police had captured the offending and shared the material with law enforcement agencies through INTERPOL.
Officers discovered that the same username had been used on an adult pornography website, where Welsby had posted intimate photographs of himself posing naked or wearing women's lingerie. Investigators spotted visual similarities between Welsby and the man shown abusing children in the offending images, leading to his identification. But with the original device used to create the images no longer available, investigators needed specialist evidence to establish that Welsby was responsible.
Forensic Breakthrough
The NCA then commissioned two experts to examine the material. A forensic anthropologist compared images of the offender with photographs of Welsby, including pictures he had taken of himself and images captured while he was in custody. A digital forensic expert separately analysed the images to establish which camera had been used to take them.
Together, the findings linked the abuse images to the same specific device as other photographs known to have been taken on one of Welsby's phones. The evidence helped prove that he was the person responsible for the offending, despite the device having been destroyed years earlier. The case marked a significant use of digital forensic evidence, allowing investigators to connect images to a specific device rather than relying solely on its make and model.
Predatory Sexual Offender
NCA Senior Manager Jen Cruickshank said: “Darren Welsby is a predatory sexual offender who inflicted the most horrific sexual abuse against children, some as young as six, over a period of eight years.
“It is impossible to imagine the trauma they suffered as a result of these monstrous crimes, and the emotional scars they’ve been left with.
“Our investigation was painstaking and time-consuming; utilising innovative forensic techniques to identify Welsby, who attempted to hide his offending by using the dark web. This comprehensive investigation ensured that necessary evidence was secured to bring him to justice.
“This sentence is testament to the skill and unwavering dedication of investigators in the NCA and we will continue to pursue dangerous offenders like Welsby, who prey on those who are vulnerable, to protect children from sexual abuse.”
Bethany Raine, Specialist Prosecutor for the Crown Prosecution Service (CPS), said: “Darren Welsby has been imprisoned for sexually abusing children, including the rape of a girl under 13. He took images of some of these terrible crimes.
“This was a landmark case as the expert digital forensic evidence proved that those images were taken on the same device as other images, known to have been taken on one of Welsby’s phones. Another expert report confirmed that the hands shown in some of the images were Welsby, by comparing them to photos of his knuckles.
“This has been a complex and challenging case due to the unique evidence needed to bring Welsby to justice. It would not have been possible without the comprehensive investigation undertaken by the National Crime Agency.
The Crown Prosecution Service is committed to tackling child sexual abuse and to supporting victims through the criminal justice process.”
The CPS has a dedicated national Organised Child Sexual Abuse Unit, where specialist prosecutors handle complex cases and work to secure successful prosecutions against offenders.
