A teaching assistant shared naked photos with a teenager on Snapchat after calling him a 'good lad'.

Chelsey Knox, 33, shared videos of herself in the shower as well as two topless pictures and a picture of herself using a sex toy with the 16-year-old.

After the two started messaging the mother asked for him to send pictures of his genitals.

The teaching assistant also admitted two counts of causing a child to watch an image of sexual activity and inciting a child to engage in sexual activity.
