Tech giants Google and Microsoft announced in a joint statement that they will perform a worldwide block on search results linked to child abuse.

According to the Mail, Google assembled a 200-strong team of engineers to work on "state-of-the-art" technology to fight the problem after United Kingdom put pressure on the search engine companies.

"We've fine-tuned Google Search to prevent links to child sexual abuse material from appearing in our results. While no algorithm is perfect - and Google cannot prevent paedophiles adding new images to the web - these changes have cleaned up the results for over 100,000 queries that might be related to the sexual abuse of kids," he told the Mail. "As important, we will soon roll out these changes in more than 150 languages, so the impact will be truly global."

Last week, 348 people were arrested and 386 young kids rescued in Canada, after one of the largest child sex investigations succeeded raising concern and hope among governments and tech companies.
