What should I do if I think I'm being followed?
I think the important thing to do is to stay in or make your way to an area that is well lit and where there's other people around that will give you confidence in your surroundings. If you still feel you are being followed, then going to a shop or somewhere else where there's lots of people. If you still feel someone is lurking around you, you really are concerned, then there is always the option of calling the police if you really do fear for your safety. I think the key message is, if you feel you're being followed, don't stop moving away from well-populated or well-lit areas until you feel certain that is not the case.
