They issued a message on Halloween to parents asking "do you know where your children are tonight?".
"We are appealing to parents and guardians to be aware of where their children are, who they are with, and what they are doing.
"While the vast majority of young people are respectful and well-behaved, a small number of incidents like these place others -- and Garda members -- at risk.
"Please take a moment tonight to check in, make that call, and ensure your children are safe and accounted for. Community safety is everyone's responsibility. Let's work together to keep our towns and villages safe for all."

"Every year, fireworks and bonfires cause injuries, fear, and damage in our communities - not to mention the distress caused to pets.
"Fireworks are illegal, and the penalties are serious. This Halloween, don't take the risk. Let's keep our communities and families safe".
