Gardaí are encouraging victims of cyberbullying to come forward and report the crime to the authorities.
The force says people who are bullied online can help provide the evidence needed to ensure others do not become victims.
They stress that cyberbullying has the ability to destroy lives.
They're advising parents to know what sites their child is visiting.
Parents who find out their child is being bullied are advised to print out and keep evidence of the bullying, as well as blocking the culprit.
However, they're urged to not delete any accounts in order to keep any evidence that might help gardaí.
Detective Chief Superintendent Declan Daly said: "If you do decide to give your child permission to use social media sites, the best online safety strategy is to talk with your child and engage with their use of the Internet."
Young people, meanwhile, are being advised to think before they post anything online, as anyone could see, share or screenshot posts.
Gardaí suggest: "Only post messages you wouldn’t mind your parents or teachers seeing. Remember whatever you share online stays there."
Any child or teenager being bullied is encouraged to tell a parent, guardian, teacher or an adult they trust.
