According to Metro, Lisa Mackenzie of Wales discovered strange scratches on her back door. Therefore, this mother of two installed a security camera to get to the bottom of the mystery, yet never expected it to capture something so disturbing. Watch the frightening footage as a man lurks in her backyard, shines a light into the house, and even tests the doorknob – all while she and her two children were sleeping upstairs. 

Metro reports that the video is now going viral and police are using it to try and identify the burglar. We're just glad Ms. Mackenzie and her children are safe and that local law enforcement is involved in the case. Have you ever experienced any sort of home invasion?
