A 24-year-old man has been arrested and released on bail after a video emerged allegedly showing Scotland and Sheffield United striker Oli McBurnie involved in a street fight.
The video, widely shared on social media, appears to show a man approaching a group, with one person recording the incident on their phone.
The phone is then stamped on, with the altercation leading to a brawl before a voice can be heard saying: "Take your boy away now."
North Yorkshire Police confirmed a 24-year-old man from Knaresborough was arrested "in connection with an incident, which involved another man being assaulted".
The statement added: "The 21-year-old victim sustained facial injuries during the incident, which happened shortly before 8.30pm on Saturday 8 May on High Street in Knaresborough."
Sheffield United said in a statement: "Officials at Sheffield United are aware that Police are now involved following the emergence of a video circulating on social media over the weekend and as a club we will do all we can to assist enquiries, as well as continue our own investigation."
The injury means McBurnie is a major doubt for Euro 2020, with Steve Clarke having to submit his squad for the tournament by June 1. Scotland begin their Group D challenge against the Czech Republic at Hampden on June 14.
