Jason Tilbury believed he’d been sending sexual chats to a 15-year-old girl named Holly via social media – and sent pictures of his penis.
But Holly was a fake profile set up by paedophile hunters Dark Justice to snare online sex offenders.
The 50-year-old asked to exchange pictures of their bodies, requested photos of her “cleavage”, sent her an image of his genitalia and asked her to do the same.
They agreed to meet at Newcastle railway station and he offered to pay her train fare during the chat between March 19 and 24 last year.
He told her it was a “big risk” for him because of her age.
Tony Cornberg, defending, said Tilbury ended up “completely out of his depth” feeling regret, shame and embarrassment.
He said: “He in fact cuts a rather feeble, perhaps pitiful and lonely figure.”
Tilbury was jailed for two years and three months.
He was also given a sexual harm prevention order banning unsupervised contact with children and regulating his use of the internet and devices, and will be on the sex offenders’ register, both for 10 years.
