Another Northern Ireland fan has died at Euro 2016.
A man in his sixties collapsed during their 2-0 win against Ukraine in Lyon.
Paramedics were unable to revive him.
The PSNI's Nigel Goddard said; "Our thoughts are tragically with a second family this week mourning the devastating loss of their loved one.
"We understand the man aged in his sixties collapsed during the game and was attended to by emergency services in the Stade de Lyon. It is extremely sad that this is the second death of a Northern Ireland fan in France during the Euro 2016 games.
"We have been liaising with French Authorities and local PSNI officers have been in touch with the man's family in Belfast," he added.
The players wore black armbands during the game to mark the death of 24-year-old Darren Rodgers, who died on Sunday after a fall in Nice following their loss to Poland.
FAI President Tony FItzgerald said today: “I would like, on behalf of the Board of the Football Association of Ireland, to pass on our deep sympathies to the Irish Football Association and to all those involved in Northern Irish football.”
FAI CEO John Delaney said: “This is a sad outcome to what was a historic day for Northern Irish football following their victory over Ukraine.
“On behalf of everyone in the FAI and the Republic of Ireland squad, I would like to express our sadness and condolences to IFA President Jim Shaw, CEO Patrick Nelson and all who are associated with the Northern Ireland squad.
“We also remember the friends and family of another Northern Ireland fan Darren Rodgers who died earlier this week in a tragic accident in Nice, and we would also like to remember Republic of Ireland supporter James Nolan, who died four years ago in Poland, during EURO 2012."
