Police have launched an investigation after a video shared online appeared to show Newcastle United fans attacking an Arsenal supporter sitting in the home end of St James' Park over the weekend.
The Gunners visited Newcastle on Sunday afternoon in a clash between second and third place in the Premier League, which the London side won 2-0.
On Monday morning, a short video shared by Twitter account Away Day Sleepers showed the melee in the St James' Park stands.
A number of Newcastle fans appear to grab the Arsenal fan in a bid to remove them from the home supporter section as children are heard screaming in the background.
The video was then shared by Football Away Days, who have over 270,000 followers and has now been seen by over six million people online.
On Tuesday, Northumbria Police confirmed to NewcastleWorld that they were working with the football club to establish a course of action.
A Force spokesperson said: “We are aware of a video circulating online in which a male was ejected from St James’ Park.
“Enquiries into the incident are ongoing and officers are working closely with the club to establish if any offences have occurred.”
Arsenal won the meeting between the two sides thanks to an early Martin Odegaard goal and a Fabian Schar own goal in the second half.
The victory means Mikel Arteta's side keep the pressure on Manchester City in the Premier League title race with a gap of just one point, although the Champions also have a game in hand.
The Magpies' first loss since April 15 ended a three-match winning run but the side remain two points of Manchester United in fourth and three points ahead of Liverpool in fifth.
