Siah Riley, 35, from Derby, admitted a raft of sickening sexual offences and blackmail against dozens of children who he contacted using a fake online profile
A man who pretended to be a teenager on Snapchat to convince more than 150 children to send him sexually explicit videos and images has been told he’s “every parent’s worst nightmare” as he was jailed for 25 years.
Judge Shaun Smith KC told convicted rapist Siah Riley he had never come across such a prolific offender of his kind throughout his 46 years in the legal profession.
The 36-year-old defendant masqueraded as teenagers by setting up fake social media profiles, luring girls as young as nine into sending him sexual videos and images.
When some of his victims refused to bow to his demands, the paedophile threatened to circulate the material they had already sent him across the internet unless they supplied him with more.
When officers finally tracked down the depraved offender, they discovered he had meticulously catalogued the footage and images into files sorted by his victims’ names, according to Derbyshire Live.
Handing down a 31-year sentence, Judge Smith said: “This was depraved. The extent of your obsession with online pornography involving young girls is truly breathtaking.
“You have no moral compass. You are every parent’s worst nightmare.
“In my 46 years in this profession, I have never encountered a case with so many offences and so many victims. In one video you told a girl to choke herself so she knew you were in charge.”
Leanne Summers, prosecuting, said the offending stretched across a two-year-and-eight-month period between 2021 and 2023. She said: “This case is about the defendant’s prolific use of Snapchat to incite children aged nine to 16 to share with him sexual images and videos.
“The total number of victims is 152. He used two Snapchat accounts.
“One was under the name Josh King in which he pretended to be a teenage boy and another under the name Kim in which he posed as a teenage girl. On each occasion he used Snapchat accounts to request images of a sexual nature.
“His attitude towards them often changed when they became reluctant and he blackmailed 24 victims saying he would share their images online if they did not carry on sending them.
“His method was to use one device to chat to the victims and another device to record what was sent to him. He then moved them to a laptop, storing them there under the names of the victims. It is clear they do not know he was using a separate device to record them.
“When police seized his devices, there were also indecent images of children, including 1,831 images of his victims, which he retained for his own sexual pleasure.”
Miss Summers outlined numerous disturbing examples of the videos and images the young girls had been coerced into sending Riley. Among them was a 13-year-old girl who referred to the defendant as “Master” and apologised for “not doing better” for him.
He then proceeded to blackmail her, threatening to upload the videos to TikTok, Facebook, pornography sites, the dark web and “everywhere he could” if she refused to keep sending them. The prosecutor revealed that when a further blackmail victim told him she was just 10 years old, he responded: “I don’t care, you are hot.”
He also told a third victim that he “hoped her parents would see” the images he was threatening to post on Facebook.
Miss Summers read out a number of victim impact statements in which the young girls described how their personalities had been “destroyed” and how they feel they have “betrayed themselves”.
One mother’s statement read: “My family will never forgive and forget what you have done because every time I see the scars on my daughter’s arms it makes me hate you a little more.”
Riley’s prior criminal record includes a conviction for rape dating back to 2012, for which he was handed a six-and-a-half-year prison sentence.
Steve Gosnell, mitigating, said his client had entered guilty pleas to the string of charges at the earliest opportunity. He said: “He does regret this and he does apologise. He knows he will receive a term of incarceration of many years.”
Alongside the substantial prison term, the judge also handed Riley a lifetime sexual harm prevention order, as well as a permanent place on the sex offender register. The 31-year sentence comprises 25 years’ custody plus a six-year extended licence.
