At Oxford Crown Court this week, the 20-year old of The Holt, Abingdon, admitted a total of 15 counts relating to inciting children to engage in sexual activity, making indecent images of children and voyeurism.

At his sentencing there on Wednesday, prosecutor Laura Blackband said that after his arrest Thames Valley Police found the largest haul of indecent images of children the police force had ever seen.

Detailing his offending, she said that Rickett, who was a film maker, used the persona of a fictional young girl called ‘Millie’ to groom his child victims.

On Instagram he befriended numerous boys, some as young as nine, and asked them to perform sex acts.

In one instance detailed to the court a boy asked to lick a toilet seat and perform other acts, unaware that Rickett, a man nearing his 20s, was the receiver of the images.

Th cases were reported to police and Rickett was arrested and released before he went on to get a job at the Tesco superstore in Cowley in August last year.

In October, he again filmed boys in a toilet, this time at Thorpe Park, where he was arrested.
