A man who sent a video of a naked teenage boy to his mother after threatening to expose him has been jailed for a catalogue of offences.
Mark Anthony Wilson, 35, targeted nine vulnerable children and young adults across the UK through social media, asking for sexual photographs and videos.
He then threatened to expose his victims, aged between seven and 19, and their families if they did not give into his "sickening" requests.
Wilson, from Stokesley, North Yorkshire, was jailed for six years and eight months at Teesside Crown Court on Wednesday after pleading guilty to all 27 offences at York Magistrates’ Court.
His charges included making indecent images of children, distributing an indecent photograph of a child, sexual communication with a child and causing or inciting a child to engage in sexual activity.
In one of the incidents, which took place between 2018 and 2020, Wilson sent a video of a naked teenage boy to his mother.
Officers also recovered images and video of a seven-year-old boy’s genitals sent during a series of 206 messages and Facetime calls between Wilson and the victim.
Police found explicitly sexual images of a girl, eight, and 1,149 messages between Wilson and the victim, many of them graphically sexual.
Wilson also sent racially offensive, abusive and sexual messages to a 16-year-old girl, threatening to post videos on YouTube claiming her father had raped her.
He received an uplift of nine months to his sentence for the racially aggravated aspect of this offence.
Wilson was also handed an indefinite sexual harm prevention order.
Detective Constable Karen Barugh, of Northallerton CID, said: “The defendant has committed multiple malicious and sexual offences against children online between 2018 and 2020, causing them great distress. They must have been terrified at the thought of him carrying out his threats.
“Despite being arrested, he continued to commit offences while on bail, his offending increasing in severity over time. He was prolific in his targeting of children and has shown no remorse for what he did.
“I'd like to thank those children and young people who were brave enough to come forward and give a statement to the police.
“I would urge anyone else to do the same if they are victim of any type of sexual offence.”
