Hearts have apologised after ‘The Sash’ was played over the PA system at Tynecastle during an open day.
Fans were enjoying tours of the stadium on Sunday when the loyalist song was heard, before videos of the incident were later shared on social media.
The club said the PA system was switched off as soon as it was made aware of the issue.
Officials also apologised to those inside the stadium at the time and said the “song in question has no connection to Hearts and it has no place at Tynecastle”.
Hearts said: “The club would now like to further extend that apology to our wider fanbase after videos of the incident were shared on social media.
“Procedures have already been implemented that will ensure such an incident is never repeated.
“The FoH (Foundation of Hearts) Open Day was an extremely proud occasion for the club and we would like to, once again, thank our supporters who continue to back every aspect of the club in tremendous fashion.
“We look forward to welcoming everyone back to Gorgie for this Saturday’s cinch Premiership encounter with Dundee United.”
