Footage has emerged on Facebook, of two teens fighting with a 51 year old man on a subway train, before the fight takes a nasty turn when they attempt to push the man off the moving train.At 1:35, one of the teens is seen pushing the old man towards the door of the moving train, opening it partially, before calling for help to open the door fully.Even as the old man struggles, the girl recording the video continues her pointless narration while the man's life is threatened. Baltimore police are reportedly in possession of the video content.
