Lee McLaughlin (19) from Inishowen, Co Donegal, arrived in Paris on Sunday with his father and another family member, and was due to fly back home to Ireland yesterday.
They attended Ireland’s opening Group E match v Sweden at the Stade de France on Monday evening before they returned to their hotel in Montmartre a number of hours after the game.
Sometime before midday on Tuesday Mr McLaughlin is believed to have left the hotel on his own, and he has not been seen since.
FAI CEO John Delaney has been in touch with the McLaughlin family and has offered every assistance and support to the family, including the activation of an extensive communication and social media campaign to help locate Lee.
The FAI has today communicated with the Confederation of Republic of Ireland Supporters Clubs and has sought its help in locating Lee.
