Google 'should be proactive' on porn

Search engines such as Google should do more to restrict access to online pornography, a government adviser on child internet safety has said.

John Carr said increasing the number of sites automatically blocked by search engines would make it more difficult for paedophiles to get images of abuse.

It comes after a court heard pictures of child abuse were on the laptop of April Jones's murderer Mark Bridger.

Google said it has a "zero tolerance" policy to child sexual abuse content.

Speaking to the Today programme's Sarah Montague, Mr Carr said that "Google... can and should be proactive" when it comes to censoring websites that show hardcore pornographic images online.
