A lawyer representing the boy's family accused police of ramming a patrol car into his motocross bike during a high-speed chase on Wednesday. Prosecutors said that they were treating the incident as "unintentional" and were looking for videos to ascertain the facts. The crash happened just over two months after police shot and killed a 17-year-old of North African descent at a traffic stop in the Paris suburb of Nanterre. The tournament, one of the major events on this year's international sporting calendar, kicks off on Friday when France play New Zealand at the Stade de France near Paris.
