There were shocking scenes in the Welsh lower leagues yesterday after a video emerged of amateur outfit Cefn Druids fighting their own fans.
The Wrexham-based outfit went down 7-0 against Caernarfon Town - who were subsequently crowned champions - and that was enough to spark an exchange between players and fans of the former's commitment.
One Cefn player, who Wales Online say had just been sent off, was seen arguing with the club's supporters on the side of the pitch - and then the confrontation suddenly and violently escalated.
Other players then joined in the fight alongside more fans, resulting in an all-out brawl that was captured by Greg Evans from Wrexham, and subsequently posted online. You can check it out at the bottom of this article.
Now it has been confirmed that North Wales Police will investigate the incident, and have called on anyone present to come forward and give their version of events.
Supt Gareth Evans said: "We share the disappointment of law abiding fans present at the match where violence broke out. An investigation is under way and I would like to thank the fans yesterday who assisted officers with establishing what had occurred.
"Anyone who directly witnessed or were the subject of any threats or violence should contact us on 101 if they have not already done so.
"Similarly, if you recorded what happened on a mobile phone please get in touch. It is clear there were a number of people involved. The investigation will look at all aspects of the incident and I ask for patience while officers work through this information, speak to witnesses and view CCTV and mobile phone footage."
Neither club have commented on the brawl.
