Police have urged parents to snoop on their children’s Snapchat profiles to prevent grooming, as it emerged that the suspected paedophile accounts which officers have warned against remain active.

Several schools in Berkshire have written to parents asking them to check their children’s social media for any contact with the users “CraigDavis1999” and “James Hammond”, which they suspect are targeting youngsters in the area.

Thames Valley Police told The Daily Telegraph that they issued to alert to parents as part of an investigation into “sexual grooming”.
