Ross County are investigating “an incident of sectarian behaviour” from their own fans during Wednesday’s match against Celtic.
The Dingwall club said the incident occurred after the dramatic end to the Premiership match at the Global Energy Stadium, when Celtic scored deep into injury time to win the match 2-1.
County said they were working to identify those involved and have already made the police aware that a criminal investigation may be needed, with the club promising the strongest possible action.
A club statement read: “Ross County Football Club are aware of an incident of sectarian behaviour which occurred within our singing section after Celtic scored the winning goal on Wednesday night.
“We strongly condemn this type of discriminatory behaviour and language, which has no place in football or wider society.
“We are working to identify the individuals involved and will take the strongest possible action against them. An investigation is underway within the club and Police Scotland have been notified with a view to carrying out a criminal investigation.
“Any supporter who was present in that area of the ground and has information or recordings that can assist this investigation should contact the club.”
Police are already investigating several incidents of alleged disorder among Celtic fans during the game.
One man, aged 32, has been arrested and charged. Celtic fans spilled on to the pitch as they celebrated the late winner.
County manager Malky Mackay gave strong backing to Ross County’s stewards after two of them were injured in the pitch invasion.
“I thought Ross County stewarding and staff did everything they could in the circumstances,” he said.
“It is disappointing obviously that one steward ended up down stairs and another one with a broken wrist.
“So that’s not great, considering they are trying to do their job. That is something that has maybe got to be looked at.”
