Nicki Minaj Stops Concert After Fan Gets Maced, Posts Booty Popping Video After

Nicki Minaj's concert might as well have been billed as a fight night.

During the Bay Area stop of her Pinkprint Tour at the Concord Pavilion, about 33 miles west of San Francisco, on Friday night, a number of physical altercations broke out.

Things got so bad in the packed venue that one female fan reportedly got maced. Minaj went as far as stopping her show and calling the girl on stage.

In a cell phone video posted by a fan, the visibly upset rapper can be seen yelling out "stop, stop stop" as she asks if anyone has water and to help the injured girl.

One of Minaj's die-hard fans witnessed the incident and posted about his disappointment on Saturday. "Still sad about the ratchet concert behavior last night," he tweeted. "4 girls jumped this poor girl & she peed herself when they were beating her up."

According to the Concord Police Department, a number of concertgoers required on-site medical attention after the pepper-spray incident. A 22-year-old man from Antioch, California, was also arrested after he assaulted a Pavilion Security, who was treated for his injuries at a local hospital.

"Aside from these few unfortunate events, the concert, and vast majority of the crowd, were not affected," Lieutenant Tim Runyon said in a statement to ET. The case remains under investigation.

Minaj, 32, has not publicly commented on the incidents, but she did post a photo on Instagram after her show, saying the crowd was "more than turnT... Let's just say that. Lol. Can't wait to see u guys again."

In the last 48 hours, the majority of the "Anaconda" rapper's social media comments have been reacting to fans support and outrage after she posted a video of Meek Mill staring at her behind as she booty pops.

"I love how we spend our days off," she wrote, tagging her boyfriend. "Cheers to everyone living their lives and not being pressed."
