A grandmother believes she's captured the 'ghost of a war criminal soldier' in her garden.

Lael Robertson, from Queensland, Australia, was at home when her dogs began barking erratically.

Lael, 51, checked her cameras and was gobsmacked when she saw an image of what she says was a 'human-like' figure lurking near her porch.

Lael believes what she saw was the shadow of a war criminal soldier.
