Usain Bolt was knocked down by a cameraman in Beijing on Thursday, 27 August, shortly after winning the 200m sprint at the the 15th IAAF World Championships at the National Stadium in Beijing. The fastest man on earth was taking a victory lap at the Bird's Nest, with a Jamaican flag wrapped around his shoulders, when the collision occurred.

A cameraman, who was riding a Segway, lost balance after the wheel went over a camera track and crashed into Bolt, bringing him down. It also caused the scooter to turn abruptly to the right and clip Bolt from behind.

Just as Bolt fell, another cameraman rushed to help. The good news is that Bolt and the cameraman were not injured in the collision. The Jamaican star did a backward roll and was back on his feet -- he briefly rubbed his ankle before continuing to celebrate with fans.

In an interview with BBC, Bolt joked about the incident saying: "They tried to kill me." The sprinter later told reporters: "Accidents happen. I have a few cuts, but it is nothing that I have never done to myself in training. I will be all right."

Usain Bolt won the 200 metres event at the the 15th IAAF World Championships at the National Stadium in Beijing, on 27 August, clocking a time of 19.55 seconds with Justin Gatlin coming in second.
