LONDON (Reuters) - Snarling football supporters pelted each other with ripped-up seats and coins at West Ham United's game with Chelsea on Wednesday, in the very stadium where peaceful athletics fans cheered Britain's Olympic heroes four years ago.
The eruption of hooliganism, a phenomenon the English game hoped it had consigned to history, has worried the Football Association enough to launch an investigation. It will ask whether the scenes reflect a problem with the former Olympic stadium itself or are indicative of a wider malaise.
