Usain Bolt knocked down in Beijing - in pictures

Bolt was celebrating his win in the 200m sprint at the World Athletics Championships when the cameraman lost control of his motorised scooter as it rolled over a post and crashed into the runner's legs.

The Jamaican did a backward roll and got back on his feet - he briefly rubbed his ankle before continuing to celebrate with fans.

He 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."
