Usain Bolt is the fastest man in the world, and his momentum at the Diamond League in Oslo couldn't prevent him crashing into a flower girl.

The Jamaican's collision with the girl ended up with the flower bearer losing her balance as he attempted to prevent her from tumbling onto the running track.

Bolt took victory in the men's 100m at a time of 9.79 seconds, finishing clear of Asafa Powell, who came second in 9.85 seconds.
