David Chellapah, 31, was under investigation after police had intel that he was chatting with a child online and tried to meet and sexually abuse them last year.
The offences took place between August and October, the Metropolitan Police said.
He was arrested on October 17 after officers intercepted a pre-arranged meeting with a child.
His mobile phone and other devices were searched, with police discovering he targeted multiple children across social media platforms.
He sent sexual messages, inciting children to engage in sexual activity and tried to arrange further meetings.
Multiple victims were identified, with some children coerced and pressured to produce sexual images and videos.
Searches of Chellapah’s home address led to several devices being seized, including a USB stick containing a significant volume of indecent images and videos of children.
Some material involved very young children, the Met said.
Chellapah pleaded guilty to all counts on February 27 to 21 offences – including sexual communication with a child, attempting to meet a child following grooming, inciting a child to engage in sexual activity, and offences relating to the production and possession of indecent images of children.
Appearing at Isleworth Crown Court on Friday (May 22), he was sentenced to 10 years.
DC Alan Stepkowski-Fellows from the Met’s Central Specialist Crime Command said: “Chellapah showed clear and persistent predatory behaviour, targeting children online and attempting to escalate that contact into serious harm. Our officers acted quickly to intervene, prevent further offences and bring him before the courts.
“Safeguarding victims remains our priority. We worked closely with partners to ensure all children were protected and supported, with specialist officers using trauma-informed approaches. We also secured strong digital evidence so victims did not have to attend court.
“We will continue working with partners to protect children and hold offenders to account.”
