Police Clear Out Thousands of Fans at Kanye West Pop-up Show in New York City People crowded the streets and sat on cars, damaging several of them.

 -- What was billed as a surprise Kanye West show in New York City quickly turned to chaos overnight as thousands of fans descended on the venue.

An estimated 3,000 to 4,000 people swarmed Webster Hall, which holds 1,500 people, in Manhattan’s East Village early this morning for the pop-up show, police said.

West had hinted on social media that he was going to do the show after his performance scheduled for the Governor's Ball on nearby Randall’s Island Park was canceled Sunday because of inclement weather.

The secret show was supposed to start at 2 a.m. and, according to West's Twitter page, was sold out by 1 a.m.

Video had poured in on social media showing dozens of people standing on cars, dumpsters, fire escapes and even a postal truck, trying to get a glimpse of the rap star.

But shortly before 2 a.m., Webster Hall tweeted that there would be no show because of the out-of-control crowds that had formed outside the site.

But West then briefly appeared outside Webster Hall at around 2:15 a.m., circling the block while waving to throngs of cheering supporters through his sunroof and shaking hands with fans, who chased him down Third Avenue. Ultimately, West never got out of the vehicle because of security concerns and left without performing.

Police then worked to disperse the crowd soon after. One person at the scene was arrested for disorderly conduct, according to an official.
