There has been a rise in use of webcams and live video streaming for sexually abusing children, according to a new report. It found that vulnerable children in developing countries were often targeted by abusers over the internet.
Speaking to Daybreak, he said: "The old model, with a view of meeting online with a view to meeting offline and then physical abuse taking place is actually a diminishing, these days sexual abuse of children can take place purely online."
Policing and criminal justice minister Damian Green has outlined steps he is taking to ensure that "sickening" sexual crimes against children do not remain hidden.
He said: "Police are bringing more cases before the courts and significant sentences are being handed down to perpetrators.
"But more needs to be done. Ceop is doing excellent work and we will see its capability strengthened when it is transferred to the National Crime Agency later this year.
"I am leading a new Home Office group which is urgently looking at how we better identify those at risk, create a more victim-focused culture within the police, health and children's services, improve data-sharing and address cultural barriers to uncovering abuse."
Javed Khan, chief executive of independent charity Victim Support, has said that police forces in the UK need to improve their reporting of child abuse crimes in order to build up a more accurate national picture:
It is sadly no surprise that the threat of child sexual abuse and exploitation is increasing in the UK ...
But the police service must also ask itself some searching questions. It's first priority is to prevent and detect crime.
Yet the national threat assessment has had to fill gaps because of inconsistencies in the way forces collect, record and categorise child sex abuse offences ...
Every police force must therefore contribute fully and consistently to the national intelligence picture. Only then will we have a true picture of the scale of the problem.
The Child Exploitation and Online Protection Centre (Ceop) has said it in concerned by the rise in the use of the 'hidden internet' - heavily encrypted forums and pages that allow abusers to cover their tracks.
UK daily users connecting to secret or encrypted networks increased by two thirds in 2012, Ceop reported, although not all of these will use the hidden internet for criminal means.
This number is set to reach to 20,000 by the end of this year.
In its annual threat assessment of child sexual exploitation and abuse, Ceop said that offenders tend to target vulnerable families overseas to set up live access to children over webcams in exchange for payment.
Often these families are in developing countries in areas with extreme poverty, rising levels of access to the internet and poor child protection policies, the report said.
