Dear Parents, Rochdale Police are asking schools in the borough to remind pupils and parents of on-line dangers.
Parents should be aware of the contacts children have on their devices and that they may be added to groups by other users.
Snapchat is used by criminals often posing as children and young people to request images from children.
Having regular conversations with your child about their online lives is an important part of keeping them safe online.
For information about how to best start these conversations and guidance on other popular apps, visit: www.thinkuknow.co.uk/parents.
