A car branded with the Wallace construction logo was towed from the Aer Lingus staff car park on Saturday afternoon after being parked there illegally.
It is understood the car belongs to Independent TD Mick Wallace.
He was seen at the airport’s departure lounge on Friday, where it is believed he was flying to Poland to see Ireland’s final game in the Euro 2012 championships this evening.
Mr Wallace could not be contacted for comment this morning.
A spokeswoman for Aer Lingus said the airline was informed on Saturday afternoon that the car had been left there. “Like all unauthorised vehicles, it was removed,” she said.
The car park is leased from Dublin Airport Authority, which uses a towing company to remove cars that are illegally parked. Anyone whose car is towed faces a fine of €140 as well as fees of €35 for each day a vehicle is kept in storage.
On Thursday, Mr Wallace told the Dáil he would put half his €92,000 salary towards repaying the €2.1 million Revenue debt of his construction firm MJ Wallace Ltd.
In an emotional personal statement to the Dáil about his tax affairs and under-declaration of VAT, the Wexford TD apologised for “an error of judgment” and said he would “not defend the indefensible".
He added: "The company understated its VAT liability and we were wrong to do so.”
