Veteran nature Tv broadcaster Sir David Attenborough hopes to fulfil a lifelong ambition by tracking down the Yeti.

The 88-year-old Brit has been making wildlife shows for the Bbc since the 1950s and his groundbreaking work has earned him a slew of awards, including three British Academy of Film and Television Arts (BAFTA) honours and two Primetime Emmy nominations.

During his career he has travelled across the globe to show viewers the most obscure species on the planet, but there is still one mysterious beast he is keen to find.

Attenborough, brother of revered British actor Richard Attenborough, who died last month (Aug14), says, "I wouldn't mind finding the Abominable Snowman. I don't say I necessarily believe in it. I'm saying that there is evidence. A set of huge teeth from a giant ape were found in the 1920s."

The Yeti is believed to be a massive ape-like creature inhabiting the Himalayan mountains in Nepal.
