Rangers have vowed to help police weed out the fans responsible for the sectarian chants heard during Monday’s clash with Hibernian.
The banned Billy Boys song made an unwelcome return during the Ladbrokes Championship clash at Ibrox, while another illicit song making mention of Easter Road boss Alan Stubbs was also clearly audible.
The Scottish Professional Football League has already stated it will wait to see what its match delegate has to say before deciding whether to take action against the second-tier league leaders following their 4-2 win.
But Ibrox chiefs have now admitted they were disappointed to see what they described as a “minority” of supporters taking part in “inappropriate singing”.
In a statement, the club said: “Rangers believes it is appropriate at this time to remind everyone of the club’s position on anti-social behaviour within football grounds.
“The club operates a zero-tolerance policy and continues to work tirelessly via the Follow with Pride campaign while supporting all initiatives aimed at tackling this problem.
“The football authorities and Police Scotland know the club is committed to eradicating all forms of unacceptable behaviour and it is disappointing that a minority engaged in inappropriate singing during the match against Hibernian at Ibrox Stadium on Monday, December 28.
“At every home and away pre-match operations meeting unacceptable conduct is included on the agenda with the attention of both the police and stewards drawn to the need to deal with this matter robustly.
“The club will assist Police Scotland in identifying those responsible for the unacceptable behaviour on Monday.”
In 2006, UEFA fined Rangers and also ordered the club to make a public announcement at all their home games pointing out the chanting of the Billy Boys was banned after it was heard during a Champions League clash with Villarreal.
