"John" is a convicted sex offender. "Ava" is his daughter. She was only told about her father's crimes weeks after his arrest. But the impact of those crimes could last a lifetime.

Online sex offenders receive counselling as part of their rehabilitation, as do their victims. However, there is currently no support for the families of those perpetrators – despite the devastation they have caused.

In today's Sky News Daily, our correspondent Katerina Vittozzi tells us about her in-depth interviews with both John and Ava (not their real names) and examines the system that offers more help to offenders than those they leave behind.

Anyone feeling emotionally distressed or suicidal can call Samaritans for help on 116 123 or email [email protected] in the UK. In the US, call the Samaritans branch in your area or 1 (800) 273-TALK.
