Police forces make more than 850 arrests a month for online child sex offences in England and Wales. The majority of suspects are men who can have families living with them at the time of the offence.
Thousands of children every year now have to deal with the vicarious shame and stigma that's associated with such a crime. Families have to move, and leave schools and jobs - the trauma of which can cause warzone equivalent post-traumatic stress.
On the Sky News Daily, Sarah-Jane Mee speaks to our correspondent Katerina Vittozzi, who has spent time with Lincolnshire Police's paedophile online investigation team, exploring what is being done to support families of offenders.
And Sarah-Jane is joined by Heather, not her real name, whose partner was convicted of online child sex offences and has now gone on to campaign for more support for non-offending family members.
