JAKARTA, March 30 — A mysterious half-naked being was spotted running down road by a group of dirt bikers in Banda Aceh, Indonesia.

The video was caught on a helmet-cam and uploaded in YouTube by Fredography last Wednesday.

The motorcyclists were riding down a dirt track in a local forest when out of nowhere, a small human-like being leap out of the trees and startled the riders. It appeared bald, topless and held a large stick in its hand.

The mysterious figure — which appeared just as startled as the riders —immediately ran off down the dirt road in superfast speed, slipping into some bushes and disappearing into the middle of the forest.

The video has since gone viral and has garnered more than 5 million views in just over a week, with some users sharing theories about what the figure could actually be.

One such theory is that the figure is likely a member of the mythical Mante tribe, which according to local urban legend, are said to be forest dwellers much smaller than the average man. They’re also said to be elusive and flee from human contact.

Last year, Indonesia was also shaken up with video footage of another mysterious being, said to be a possible sighting of the legendary Bigfoot walking through a waterfall and mountain range.
