Usain Bolt helps raise money to protect cheetahs

Olympic champion Usain Bolt has tried to help raise money for the Zeitz Foundation and the ZSL London Zoo, who are aiming to save cheetahs and African wild dogs.

The Jamaican sprinter hosted the fundraising gala in the capital and British rapper Wretch 32 was also in attendance to lend his support to the cause.

ZSL's development director James Wren said: "We are absolutely delighted that the world's fastest man joined ZSL in championing the cause of the world's fastest animal."

Bolt donated the running top he wore when he clinched the gold medal in the men's 100m final at London 2012.
