This is kind of scary - because I don't think it's a prank. This is security footage of a woman who seems to be waring some kind of restraining device. She apparently rang doorbells of five different homes, and then disappeared. She looks like she's only wearing a shirt... no pants, or shoes. Her facial expression may represent she's in some kind of distress.
Police are concerned; even though she doesn't seem to match anyone in the missing persons database.
