Paul Woodward , a primary school head, has threatened to report parents to social services if they allow his pupils to use Facebook and other networking sites.  He is concerned that youngsters who use the sites risk being exposed to inappropriate material and online grooming.

He has warned parents that persistently letting children flout Facebook’s 13-plus age rule could warrant investigation by child protection teams and he estimates that at least 60 per cent of the 270-plus children at his school in the Forest of Dean have access to social networking sites.
