This incredible security footage captures a real-life hero pulling off a true act of courage. The footage is of the Metro in Madrid, Spain, and features a man who is not paying proper attention as he wanders close to the edge of the platform. Just as he tumbles backwards onto the tracks, a train starts approaching. As locals try to alert the oncoming train, one man hops onto the track, rouses the victim and drags him out of the way of the train at the last possible second. According to the poster’s description, the man happened to be an off-duty cop.
