Scores of teenagers start smashing up a Subway shop near Dagenham Heathway, East London, late Friday. <br /><br />Sirens flare as the filmer says "they're all going to run now the Old Bill's coming." <br /><br />"It wasn’t gang related," he told Newsflare. "Just think it was for them to post on social media to hype themselves up – members of the shop [staff] were cut to the face due to smashed windows."
