I found out later from the woman who sent the video to me that she had been given three years on the sex offenders register.
'One day, just after I had dropped my son off at school, I was sent a horrific video on WhatsApp. It made me question how images and videos of child sex abuse come to be made, and how they can be openly circulated on social media. And I wanted one answer above all - what happened to the boy in the video?'
