POLICE have warned children and parents to be aware of the risks involved in social media in the wake of Ronan Hughes's death.
The PSNI has said not to share personal information or images or accept friend requests from strangers when online.
It warned children not to post anything online they would not be happy to be shared "particularly nude or nearly nude images or videos".
"It may seem like a bit of fun with friends at the time but there is always a chance those images could be shared or get into the wrong hands and could lead to harmful situations such as stalking, abuse or blackmail," police said.
Police warned children to set privacy settings on all their devices and to tell an adult if they receive any inappropriate images or links.
"The internet can be a great place but it is important to remember there are people out there who may wish to abuse, exploit, intimidate or bully you online if this happens to you, tell someone immediately," police said.
Parents have been asked to talk to their children about the benefits and dangers of the internet.
They have been warned to monitor their children online and educate themselves about internet basics.
Facebook itself has a set of community standards which outline the limits of acceptable behaviour and content. If anyone breaks the standards they are warned or removed from the site.
Anyone concerned about another user's activity on Facebook can report it to the site.
If a report suggests a person is at risk of immediate harm, the details will be referred to police.
