CEOP is the Child Exploitation and Online Protection Centre.
CEOP help children stay safe online. If someone has acted inappropriately towards you online, or to a child or young person you know, you should report it. It may be sexual chat or someone asking you to do something that makes you feel uncomfortable or someone being insistent on meeting up. Whatever it is, if it feels wrong, it probably is.
Report it via: Online Safety
