Images showing child sex abuse - including those streamed from live webcams - are increasingly available on the internet, experts from the Child Exploitation and Online Protection Centre (Ceop) warn.

"We have to keep up with the technology, expect that's where it's going to go and stay one step ahead of the game with the offenders," he told the BBC.
