Bosses at Dundee Football Club have issued an official apology to two Celtic fans after an incident at the Dens Park match on Sunday. 

The City of Discovery club held a full investigation into the circumstances which surrounded an Irish flag being removed from advertising boards during the game, and have concluded there was "a clear breakdown in communication and decision making" on the day. 

Representatives went on to say they offered their sincere apologies to the two supporters involved. 

Video circulating around Twitter showed the Irish flag being removed during Celtic's 1-0 win.

The flag was being displayed in the away end during the Scottish Premiership clash until it was taken away.

While supporters groups voiced their disgust at the actions, Dundee said the reason was not sinister - stating simply that the flag breached rules as it was covering advertising.

In a statement, the club said: "The club would advise that the enquiries into the 'flag' incident which took place at Sunday’s match vs Celtic are now concluded.

"These enquiries have revealed a clear breakdown in communication and decision making and moving forward, this needs to be and will be addressed by the club in conjunction with all members of the event management team. Clearly, the method employed to remove the item from the advertising board was not acceptable and out with the agreed procedures for dealing with matters of this nature.

"The clubs and the two supporters involved have met and discussed the issue at great length and Dundee Football Club would wish to convey our sincere thanks for the cooperation of all concerned.

"In the spirit of the discussions which took place at this meeting, Dundee Football Club would wish to place on record our sincere apologies to the two supporters involved in this incident. We will always endeavour in future to strive to achieve a safe and secure environment for everyone here at the Kilmac Stadium at Dens Park."
