AN extremely large paw found in the woods in Massachusetts has sparked a fresh Bigfoot mystery.

Two young boys discovered the huge decomposing foot as they played in a forest and handed it in to police, who were baffled and sent it for forensic tests.

The grisly find has given Bigfoot enthusiasts new hope that the hairy beast - similar to a Yeti - does indeed exist.

They say it's the best evidence yet that the legendary ape-like creature roams the forests of North America.

A medical examiner has since determined that the appendage is not human, although it appears to have five toes.

Lakeville Police believe it may just be an extraordinary large bear paw, but are awaiting the outcome of more tests.
