SHANGHAI, July 15 (Xinhua) -- A young man sandwiched between the platform safety door and the door of a subway car in Shanghai fell onto the tracks and was killed Sunday afternoon.

    The accident occurred at 3:34 p.m. when the man was trying to board the crowded train running on the busy south-north Line One, according to the Shanghai Metro Operation Co.

    The alarm was ringing and the train was ready to move, when the young man tried to force his way into the carriage. But he could neither get in to the crowded carriage nor retreat to the platform because the safety door had closed behind him, witnesses said.

    Metro workers at Shanghai Stadium Station, where the accident occurred, called the first aid center, but the man died on his way to hospital.

    The cause of the accident is being investigated.
