A verbal confrontation between two Pittsburgh Steelers fans quickly escalated into an all-out brawl. 

Pittsburgh police and Heinz Field Security are now investigating a fight between fans that happened in the stands of a game between the Pittsburgh Steelers and the Detroit Lions on Saturday, The New York Post reports. 

In a video, an unidentified white woman was heard shouting at a Black man.

"Shut up and get the f**k out!" 

The man then appears to move the woman’s hands out of his face before she’s seen slapping him. 

A white man is then seen defending the woman while the man who was slapped, punched the pair. The entire incident was captured on video.

Pittsburgh police have since confirmed they are investigating the altercation, saying “they are actively working with Heinz Field Security on the matter."

Burt Lauten, a Steelers spokesperson, addressed the incident and laid out the team’s plan to rectify the situation, as reported by WTAE. 

"Heinz Field Management is aware of the video of an incident from last night’s game at Heinz Field,” Lauten said. “We are working with local authorities and Heinz Field staff to gather more information and identify the individuals involved. This kind of conduct is inexcusable, and we will respond accordingly once more information is obtained."

It remains unclear what sparked the altercation and if Heinz Field security removed all parties involved in the fight from the stadium.
