At least five aircraft were targeted in laser attacks as they came in to land at Dublin Airport on one night last week.
The attacks forced the pilots to take evasive action.
According to the Irish Independent, the planes were attempting to land after 9pm last Friday when laser pen attacks targeted them. It's understood the lasers are thought to have been used in the Blanchardstown area.
While none of the incidents, which can cause temporary blindness to pilots, resulted in any of the flights being forced to divert, they still caused serious security concerns, according to a number of sources.
Some of the pilots had to take a certain course of action to ensure they could land safely.
A spokesperson for Garda Headquarters said an incident was reported to Gardaí at approximately 9pm on the 2nd of December and that inquiries are ongoing.
Eoghan Corry from Air and Travel magazine says while on the rise elsewhere, the attacks are quite new to Dublin Airport;
"It's a growing problem in airports right across Europe. A laser attack is designed to blindsight the crew of an aircraft coming in."
He went on to say there haven't been any major incidents worldwide "but it is a growing problem that's been used by activists for various reasons and it has to be said just by mischief makers."
