Cork Airport was closed for a time this morning after a drone was spotted flying over the airfield.
Air Traffic Control suspended operations at around 9.45am and two aircraft were delayed in landing.
Once the drone was no longer visible services resumed.
It is illegal to fly a drone within 5km of an airport.
Gardaí responded to the report and conducted a search of the area around the airport.
They did not find a drone or observe any suspicious activity.
The Director of Operations at Cork Airport has urged members of the public to be very careful with drones and not to operate them near airports.
Speaking on RTÉ's Drivetime, Ciaran Carton said operations at the airport were suspended today for 10 - 15 minutes because of the disruption caused by the drone.
He said there are a number of penalities that could apply:
"If somebody is involved in something that is dangerous or causes a hazard to an aircraft, it's a very, very significant breach of the law and has very, very serious consequences - even if it was just through carelessness.
"When you interfere with an action of an aircraft, you are talking about something along the lines of many, many years in prison if you are found guilty and if the judge decides to impose the most serious sentence."
