An investigation by the Sunday People has found children increasingly are falling prey to paedophiles through video games.
More and more youngsters are being exploited by playing unseen opponents from around the world in various games, with the number of crime reports involving online games quadrupling in five years.
Many involve scores of sex offences against children, ranging from child pornography to sexual activity with children and even rape.
Popular games including Minecraft, Clash of Clans, World of Warcraft and Roblox – each with millions of users – have all been used by sex offenders to target children.

The NSPCC says the findings of our investigation are so "deeply concerning" there must be greater regulation of the industry.
We asked police forces in England and Wales to provide details of all reports of crimes involving online computer games in the past five years.
