The picture above is of Takeshita Dori in Harajuku on Friday afternoon. There is also a short video clip here which shows the heavy congestion turning into a panic. A rumour spread around 4:20pm that a famous celebrity was nearby. the message was fuelled by mobile phones and social networking services and the build up of people seemed to confirm that something was happening. In fact, it seems there was no-one around but the crush of people in the narrow street meant that no-one could move and a panic began. Dozens of police were needed to restore order and ambulances took three people to hospital although there are no details of injuries so far.
