Arsenal boss Mikel Arteta sought to ease tension with Aston Villa after victory on Saturday.
As Unai Emery's side lost sight of three points, red mist descended in the press box.
The Birmingham Mail reports analysts from either side were seen shouting at each other, requiring stewards to step in.
It's said that a member of Arsenal staff was 'kicked out', while Victor Manas, Villa analyst and former Gunners coach, was 'fuming' and had to be 'held back'.
Jay White, a radio presenter in attendance, also claimed that the Arsenal media team 'went crazy' following Martinez's own goal — apparently, in a stand 'full of Villa fans'.
Speaking to the press after the game, Arteta addressed the commotion which broke out among the clubs' officials.
The Spaniard said: "Like anything that happens in the stands. We will look at it, address it and take action if it's necessary."
