The Slovak Police training explosives incident involved a passenger on Danube Wings Flight V5 8230, a flight from Poprad-Tatry Airport, Slovak Republic, to Dublin Airport, Ireland, on 2 January 2010, that, three days later, caused an international incident due to the mistaken carriage of a sample of plastic explosive on the aircraft.

On 5 January, the area surrounding his apartment was sealed off and evacuated, while Army bomb disposal experts recovered the sample.

Baggage with the sample accidentally stuck to it was allowed to be loaded on an aircraft and flown to Dublin, departing on a Danube Wings flight at 11:00.

[5] The police officer on duty, after realising his mistake, informed the Poprad-Tatry Airport flight controllers and in turn the pilot of the plane.

[5] The man who had carried the explosives was detained under Section 30 of the Offences Against the State Act 1939 and brought to the Garda station in Mountjoy.

[7] Dermot Ahern, Ireland's Minister for Justice, Equality and Law Reform ordered an immediate investigation into the incident.

[4] Opposition Fine Gael Senator Paschal Donohoe, in whose constituency the explosives were discovered,[12] said the whole affair was "bizarre and extremely worrying", called on the Government to offer an explanation, and praised the emergency services for their role in a safe ending.

[13] Charlie Flanagan, the party's spokesperson for justice, described the incident as "a serious security breach" which "required an immediate investigation".

[12] The Labour Party's Joe Costello called it an "extraordinary affair" and asked how the Government was going to deal with Slovakia.

[16] Online magazine forth's Jason Walsh commented: "We know airport security is a problem when European governments are planting plastic explosives on travellers".
