Facebook has been accused of encouraging grooming after an investigation revealed teenage girls are being offered middle-aged men as 'friend suggestions'.
Young girls who join the social network are given up to 300 suggestions for who they should add as friends, an investigation by The Sunday Telegraph found.
In some cases, the suggestions include middle-aged men who are topless in their profile pictures.
Facebook says it has safeguards to protect children but campaigners warn the company must do more to stop groomers who use the site to become friendly with children.
Andy Burrows, NSPCC Associate Head of Child Safety Online, told The Sunday Telegraph: "Groomers are seeking to infiltrate children's friendship groups on social networks, often with the intention to move children to livestreaming or encrypted sites where it is easier for them to commit sexual abuse.
