This week, the National Crime Agency (NCA) has announced it's launching a campaign to give parents advice on how to respond if their child becomes involved in sexting.

A significant percentage of these featured children aged 15 and under. The content is at risk of being viewed by sex offenders, with some adults encouraging children to carry out lurid sexual acts so they can view and share the material.

What's even sadder is that we're no stranger to stories like this.

Over the past 12 months, we've learnt that children as young as 11 are becoming victims of revenge porn.

And we've seen young celebrities have their private (and explicit) photos hacked and leaked on to the internet.

Worryingly, this latest report indicates that we may only have seen the tip of the iceberg, when it comes to the online sexual abuse of children.

No longer can you consider your children safe when they are in their bedroom at home: chat rooms, webcams, online dating sites and i Phone apps present a whole host of threats.

The most disturbing problem is that they arm predatory paedophiles with the tools to trawl for potential victims.

• Sexting: Serious case of young sex images 'every day', say investigators The NCA's centre for tackling abuse, CEOP Command, receives on average one report a day of a child protection issue linked to sexting.

In some instances under-18s are tricked into sending intimate photographs of themselves to adult sex offenders who then attempt to blackmail them into sending more – in what detectives have dubbed “sextortion”.

Other serious cases have involved sexual images which were sent privately to a boyfriend or girlfriend being distributed widely after a relationship turned sour. And it comes just weeks after a disturbing report by the Internet Watch Foundation (IWF) revealed that a significant number of children – some as young as seven – are posting explicit images of themselves online and allowing strangers to view them in sexual poses via webcams in their bedrooms.

Over a three month period, nearly 4,000 photos or videos were uploaded.
