Some fans at Wrigley Field on Monday got to witness a little more action than they paid for — an all-out brawl in the bleachers.

A 2-minute clip of the melee, which broke out in the left-field bleachers after the Pittsburgh Pirates beat the Cubs 5-1, shows two groups of fans fiercely going at it, wrestling and throwing punches at one another as fans spill into other rows.

It’s unclear what started the free-for-all, but one fan can be heard yelling racial slurs during and after the scrap. When the fan realizes that he is being recorded by another fan, he screams, “Don’t record me.”

At one point, three security officials try their best to break up the skirmish to little avail.

“What’s up, bitch?” one fan taunts another. “What’s up, bitch?”

Another man then injects himself in between the two groups.

“There’s no fighting in the bleachers!” the man yells. “There’s no fighting in the bleachers!”

At least one unidentified fan was separated from the group by security personnel. The commotion was coming to a close when one fan yelled a racial slur at another, setting off a second round of scrapping.

“Don’t f–king touch me,” one woman yells at other fans and security guards as she walks away from the tussle, the video shows. “Don’t f–king touch me!”

Julian Green, a spokesman for the Cubs, said no arrests were made in connection in the fight, which started about 15 minutes after the end of the game. The man who admonished his fellow fans for fighting, meanwhile, is a “bleacher faithful” at Wrigley, Green said.

“The bleacher faithful are very serious about protecting their hallowed ground,” Green told The Post. “We appreciate those who like to keep the peace.”
