Arsenal fans were pictured clashing with stewards in bizarre scenes during their 5-0 win over Nottingham Forest.
One man in a black top appeared to have his hand round the neck of a steward as tensions boiled over at the Emirates.
In another snap, one supporter is shown being dragged away while fans on the opposite side of the railing cheer.
Some 14 stewards were seen crowding around the area in a bid to calm the situation.
Fortunately, the trouble seemed to be over quickly - and instead, fans were able to cheer Tottenham's humiliation.
It was unclear what sparked the initial trouble but two fans were desperate to fight each other as fellow shocked passengers watched on.
From a video posted on social media, they can be heard yelling obscenities before aiming punches and kicks at each other.
Other passengers, presumably friends of the angry pair, were doing their best to hold them back.
As the tube stops to let people off, one of them is clearly heard shouting: "Let's go, let's go. You and your brother let's go. Now that the tube is empty let's f****** go."
