 Thousands of people overran New York's Union Square and the surrounding streets on Friday after a popular live streamer announced a giveaway event that grew chaotic, leading police officers to move in to disperse the crowd. The event was sponsored by live streamer Kai Senit, best known for his live streams on the gaming site Twitch and his YouTube videos. He had earlier promoted a huge giveaway on his Instagram account for 4pm ET. Chaotic scenes followed as people pile onto the vehicle as it leaves the scene with some people falling off the vehicle's roof onto the street.
