Animal lovers streaked naked through London Zoo on a sponsored run to help save tigers from extinction.
Many of those who took part stripped off everything and painted themselves in tiger stripes before jogging among the caged animals.
Tigers are classed as an endangered species with global populations on the decrease due to poaching and the increasing destruction of their natural habitats.
It’s believed that there are now less than 6,000 wild tigers left worldwide.
Each runner paid a £20 registration fee and had pledged to raise at least £150 to help save tigers.
