A California man has been arrested for abducting a 10-year-old child he reportedly met on social media apps Roblox and Discord, authorities said Wednesday.

Online multiplayer game Roblox is marketed at children - but there are fears it also being used for grooming.

Louisiana Attorney General Liz Murrill is suing Roblox, alleging that the online gaming platform is allowing sexual predators to victimize kids.

Roblox is a huge sprawling world of games which is sometimes described as a kind of primitive metaverse. It's one of the most popular children's games in the world.
