The game led to a lot of controversy.
Tension surrounded last week's 0-0 friendly draw between Northern Ireland and the Republic of Ireland.
Some Republic of Ireland fans were condemned as
"idiots" by their own government ministers for booing a rendition of God Save The Queen at the start of the match.
Furthermore, unionist activist Jamie Bryson was also called out on social media when he mistook a
Munster flag for a flag depicting a man in a balaclava.
Before the match, one photograph of a man holding up what appeared to be a flag bearing the emblem of the British Army's Parachute Regiment did the rounds on social media. The Parachute Regiment hold a particularly contentious place in Irish history, as the regiment's 1st Battalion was responsible for killing civilians during both the Ballymurphy massacre in Belfast, as well as on Bloody Sunday.
According to the
Belfast Telegraph, a Royal Mail spokeswoman confirmed the man's suspension from his job as a postman. She also confirmed that the matter is under internal investigation.
"The individual concerned in this case is suspended from duty until our investigation is completed and we won't comment further until then," she said.
