Barnsley FC has launched an investigation after stewards were injured in a ‘serious incident’ during Thursday’s win over Fleetwood Town at Oakwell.

A statement said the incident took place after 84 minutes. It read: “two stewards suffered head injuries and have received hospital treatment, whilst two others were treated by doctors and paramedics on site.

“This is completely unacceptable. Stewards are in place at Oakwell on matchdays for the safety of everyone within the stadium – including the players and officials on the pitch.

"Supporters are reminded that encroachment onto the field of play is a criminal offence and those found guilty of such an offence will be punished accordingly. In the case of a minor encroaching onto the field of play, in such a case, the parents or guardians of the child in question will also face a ban from matches at Oakwell.”

It is the latest in a series of fan-related incidents this year which have brought fines.

“Barnsley Football Club greatly values and appreciates support from the stands, and we thank the vast majority of the fanbase for their impeccable behaviour here at Oakwell and on our travels. But the safety of everyone attending matches is of the utmost importance and last night’s actions will not be tolerated.

“The club has a zero-tolerance policy towards any form of foul or abusive behaviour and condemns these actions - which have recently brought the Club into disrepute.

We are in dialogue with all relevant authorities, and whilst currently subject to an ongoing FA Action Plan following previous incidents at Oakwell, the potential ramifications following such an incident have been well documented.”
