Brave animal-lovers unleashed their inner beast by running around a zoo NAKED

Hundreds of brave animal-lovers unleashed their inner beast by running around Britain's most famous zoo - stark naked.

Scores of cheeky Londoners stripped off and covered themselves head-to-toe in tiger bodypaint to streak around London Zoo in a bid to raise money to save the majestic big cat.

Naked runners, who wore various tiger body paint, tails, whiskers, ears and masks, prowled around the zoo as nature intended.

The annual event, called Streak for Tigers, was held to raise funds for the Zoological Society of London's work protecting the beautiful beasts and their habitats around the world.

Young and old turned out in force at the Regent's Park zoo to show their support and feel the summer breeze through their hair - and other areas.

James Wren, fundraising director at the ZSL London Zoo, said: 'A group of tigers may be known as a streak, but sadly seeing any number of them in the wild is increasingly unlikely.

'Money raised by those who dared to bare is vital in helping us continue our work for tigers around the world, and it's definitely something to tick off the bucket list.'
