A police commissioner has said internet service providers must 'wake up' over child sex abuse images.
South Wales police and crime commissioner Alun Michael told the BBC that ISPs must take steps to restrict users access to images of child pornography following the April Jones murder trial.
The court had heard that the five year old's killer, Mark Bridger, had trawled the internet for child abuse and rape images.
Mr Michael told the BBC's Sunday Politics Wales that it was 'difficult for people to casually come across these images' but that for those who were 'determined', they were still able to.
The former Home Office minister said the UK had a good record on tackling images of child sexual abuse through the government, industry and police run Internet Watch Foundation, but that ISPs had to do more.
"It has to be said that the internet being worldwide, we need other countries to be doing what the UK is doing through the Internet Watch Foundation and we need all the providers to be doing more," he said, adding that working in partnership with internet companies was the way forward.
"I think some of the big companies really need to wake up and smell the coffee. I think it's important that they do engage and they do so quickly," he said. "They can be part of the solution. If they don't become part of the solution then they become an obstruction.
Alun Michael's comments echo those from John Carr, a government adviser on child internet safety who called last week for firms to block links which paedophiles use to find pictures of abuse.
