It’s a commuter’s nightmare. Video from Seoul, South Korea shows the moments a suspect set a packed train car on fire. Footage of the May 31st incident was released by a prosecutor’s office. It shows a man dousing the floor of the car with gasoline, prompting people to start to run for safety. One woman slips and falls in the liquid. Once the subway car is nearly empty, the suspect ignites a fire that quickly spreads across the floor. Inside Edition Digital’s Mara Montalbano has more.
