Kanye causes chaos in New York: Hundreds mob streets for star's 'secret' gig prompting NYPD shutdown and near riot... as delighted West drives through crowd hanging out the SUNROOF of his car

Chaos erupted outside Kanye West's secret concert in New York City after hundreds of desperate fans descended on the venue, forcing officials to cancel the gig. Police were called in to control the crowd as people swarmed around Webster Hall and climbed on top of cars to get a better view as rumors swirled about the gig. Kanye was heard asking for Mayor Bill de Blasio to shut down the block in a Snapchat taken by wife Kim Kardashian after a stampede outside the venue. Fans went wild and chased the rapper, who was standing out of a sunroof, when he arrived in a car, but he wasn't able to perform. Webster Hall announced there would be 'no late show'. Fans were sprayed by cops after one group smashed a window but the disturbance was brought to an end around 3.15am.
