As night fell in New York City, chaos and violent encounters fanned out once again between police and demonstrators. In Lower Manhattan, a dumpster was set on fire, forcing police officers to cordon off protesters. On some streets, there were bashed-in store windows even though some protesters had pleaded with others not to engage in looting. Around 10: 30 p.m., NYPD began making significant arrests at the Barclays Center in Brooklyn. At one point, police could be seen racing after protesters. Some observers were maced at close range. There were at least half a dozen people arrested. In one video from PIX11 News, an officer can be seen shoving a protester down a set of stairs after another threw her to the ground.
