An Armagh primary school has warned parents not to let their children play two popular computer games unsupervised.
Armagh Christian Brothers Primary School wrote on their Facebook page warning parents not to let pupils play online games, particularly Fortnite or Roblox unsupervised.
Both games are for multiple players and allow players to interact with each other online.
A spokesperson for Armagh Christian Brothers Primary School wrote on Facebook warning parents not to let their children play the games unsupervised and said that a parents' Internet safety event would be hosted soon by the school.
"If your children are playing any of the two games shown, or spending unsupervised time on any other online gaming platform, then we as a school would like to remind you of the absolute need for you to supervise what they are doing," the message read.
"In light of recent information shared with the school, we recommend that you speak openly with your children about what they do and see in online games.
"Supervision is the key! Details of a parents' Internet safety event to follow very soon."
A National Crime Agency spokesperson told The Sun "Fortnite is immensely popular with children and teenagers across the country.
"It features voice and text chat which cannot be turned off, so it's important that parents and teachers understand that risks broader risks associated with the game and enable safe playing."
However, a Fortnite spokesperson has said that users are able to disable the voice chat feature if they wish.
Roblox told The BBC that there are extensive parental controls on its games and that parents should take the time to review all settings for their child's account.
"All games on Roblox must comply with our Rules of Conduct. Our safety team reviews every uploaded image, video, and audio file used within our games to make sure they are safe and age appropriate," a spokesperson said.
"Parental involvement is critical to a fun and safe experience.
"To that end we have created extensive parental controls for our games and a detailed Roblox Parent's Guide that provides information to parents to help create a Roblox experience that's best for their child."
