Don't show people that you are the perfect victim by acting or looking weak, timid or unobservant. It is even easier to be victim to a crime if you are alone, isolated or drunk through alcohol use.
If you can make sure you always have the money for a taxi home, this way you are guaranteed a safe ride home or to a friends. Make sure you use a fully certificated taxi firm.
Make sure you always tell someone where you are going and what you are doing. If something happens to you, it is much better if at least one person knows where you are at all times.
If you go on a night out make sure you always watch your drink to be sure that no one has spiked it and if you go outside for a cigarette or you go to the toilet make sure you leave it with a trusted friend or a family member.
When walking at night make sure you always walk in well-lit areas and always stay on a main road where if you need help you can always get it.
