A nightmare played out in real life for a Hermitage woman when she found security footage of a man committing sexual acts in her backyard.

As Sheila Butler was sound asleep inside her home, the man entered her yard, stripped naked and pleasured himself. The entire trespass was caught on Butler's surveillance camera.

She didn't see the footage until after she came home from work and noticed his shirt on the fence, which prompted her to investigate further.

Luckily, Sheila's doors were locked, and the man left about a half hour later. But, whoever he is, the man still hasn't been caught.

Police are investigating the incident to find out who the man is.
