What would you do if someone attacked you? 

Could you fight back, or would you avoid resisting and wait to escape? 

Only you can decide whether to fight back, but preparing yourself for all possibilities could provide a split-second advantage. 

If someone threatens you, shout and scream for help and set off your personal attack alarm if you have one. This may unnerve the attacker and frighten him off. 

You have every right to defend yourself with reasonable force, with items which you have with you, like an umbrella, hairspray or keys. But the law does not allow you to carry anything which can be described as an offensive weapon. 

If you have been attacked, Victim Support schemes can help you cope. Ask the police to put you in touch.
