On the last Friday around 09:00 p.m., the tram line 903 arrived at the underground station “Steinsche Gasse” in Duisburg to continue the journey northwards. At that moment, people from a group of seven youths stepped outside against a closed door of the tram. The door was damaged and opened. This triggered a warning signal, which led the 50-year-old driver of the train to immediately carry out an emergency stop. This caused several passengers on the train to fall, and one passenger fell through a pane in the train (photo).A total of nine people, five men and four women between the ages of 18 and 52, were injured, mainly bruised in different parts of their bodies. Seven of them were taken to Duisburg hospitals for further treatment by ambulances of the Duisburg Fire Brigade.The fleeing youths are said to be between 12 and 15 years old, due to their external appearance all are supposed to be migrants. Witnesses are asked to report to the Duisburg police by calling 0203 – 2800.
