This is the spooky moment the 'ghost' of an ancient Thai woman is caught on camera by a group of passing motocross riders.

Jade Mungnon, 45, was riding with several pals on a dirt track when he recorded the footage on his helmet camera.

The oblivious group of motorcyclists reached end of the track and watched back the footage of their riding - only then noticing the white figure floating briefly next to a tree.

They returned to the scene to check but saw nothing - and when Jade got home and slowed down the clip it shows a female Thai woman wearing a traditional silk sarong with her hair pinned up in a bun. Her dark eyes, face, arm and shapely figure are visible as she turns over her right shoulder to look at the man filming her.

The eerie footage has now sent the chills down the hardened group of motorcyclists who are convinced it’s a spirit on the tracks in at the Khao Mai Kaew park in Chonburi, Thailand.

Jade, from Yangoon, Myanmar, said: ‘’I was riding my motorcycle and a friend was in front doing the navigation. I record everything on my helmet camera.

‘’At first I didn’t notice anything. But when we all watched back the footage there was a white shape on the screen.

‘’I opened the footage on my computer and when it is slowed down it shows a woman. People think that it's a spirit haunting the path. She is looking directly at the camera. We were shocked. It is very spooky. I have never recorded a ghost on camera before but this is very clear.''
