Kellie Howarth used to pose as a girl to trap paedophiles online. Then she grew hunted herself by internet trolls and was falsely accused of mistreating children. Was she the main victims of a vengeful child sexuality wrongdoer?

It was a few months ago, as Kellie was getting ready for a period out at the park with her young daughters, that police knocked on her door.

The 42 -year-old mother-of-four panicked. She asked the officers whether something had happened to her adult son, who lived away from home.

No, they said. We need to speak to you.

She sent her 12 -year-old upstairs and afforded her four-year-old daughter some toys to play with.
