"Please get off the bus, we need to conduct a routine check". At around 1 o'clock yesterday afternoon at the north exit of the Nanjing Yangtze River Third Bridge Toll Station, policemen with guns got on a coach with Anhui province license plates. Just as the passengers were about to finish getting off the bus, suddenly a woman wearing a pink shirt knelt in front of the policeman and cried out: "My child is still on the bus, held at knifepoint and forced not to get off, please save her!"
