How safe are your children online?

On Day 2 of GMB's special investigation into online safety, we look into privacy settings.

Young people who use social media are at risk if they post too much information about themselves, and if they do not have the maximum privacy settings.

Today, Ranvir Singh revealed to a group of young people how much information our criminologist was able to find out about them by looking at some of their social media profiles. Even the most innocent updates can give dangerous information to a potential predator.

Plus, Sophie Ellis Bextor and her mum Janet Ellis tell us why they are ambassadors for the one-stop advice hub Internet Matters.
