When coming home late at night you should always be alert. Predators use this time of the night to take advantage of the hour when no one is around and the person with their guard down due to a long work night with things on the mind. When someone approaches you at night be aware of their posture and how fast they are approaching. Often they will ask a harmless question to build trust and to get closer. Use a loud voice to yell stop and no. After you have said no and they still persist then be prepared to use force. Take control of the situation verbally or with a wristlock. It is also helpful to know where some pressure points are located.
