Free runners used as 'orangutans' in study

Parkour athletes - also known as free runners - are being used to find out how orangutans move through forests.

An assault course at the University of Birmingham has been designed to replicate the way orangutans travel by climbing and leaping.

The university said the £65,000 study would look at the impact climate change and deforestation had on the way orangutans travel.

The BBC's David Gregory reports.
