USAIN BOLT CRASHES TO THE GROUND AFTER HITTING A CAMERAMAN AT WORLD CHAMPIONSHIPS IN BEIJING

Usain Bolt jogged through the line beating his clenched fists against his chest as he defeated Justin Gatlin for the second time in a week - before being taken out by a cameraman who lost control of his Segway.

After beating American Gatlin in the 100m on Sunday, the Jamaican breezed to 200m victory in 19.55sec, the fastest time in the world this year and his quickest since winning gold at London 2012.

But there was drama on the lap of honour afterwards with two security scares. He seemingly avoided serious injury after being run over by a cameraman riding a Segway.
