A new video posted to YouTube shows a group of teens turning on a Good Samaritan who tried to break up a brutal fight outside a Williamsburg burger joint last year. Surveillance video shows two girls arriving in front of Action Burger on Graham Avenue. One girl put down her coat and pulled up her hair and within minutes a group of teens surrounded the girls egging them on. A Good Samaritan riding by on his bike decided to stop and help. The teens surrounded the man and dragged him off his bike before he broke free and got away. The video ends with a few girls pulling the victim, who was knocked out, to her feet. The fight which happened on Nov. 20, was posted recently by the restaurant’s owner Vlane Carter. This is the second teen girl fight video to go viral in the past week.
