paedophile is filmed pulling up trousers after attacking girl, 12, in park.

A paedophile who pulled a young girl off her bike before repeatedly attacking her said moments before: “You’re going in the park to do rude things.”

John Potts, then 71, dragged the young girl from her bike into bushes before pinning her down and repeatedly sexually assaulting her

Video, filmed by a group of men who came to the girl’s aid and detained Potts until police arrived, shows the horrible moments after the attack.

The pensioner, who has dementia and a brain injury, was filmed pulling his trousers up near the bushes.

He was not fit to stand trial and was detained under the Mental Health Act, with a jury finding he committed three of four alleged acts – two sexual assaults of a child under 13 and inciting a child under 13 to engage in sexual activity.
