A hate crime happens when a person is targeted because there is a hostile attitude or prejudice towards their:
race or ethnicity
religion or belief
Hate crime is a form of harassment that is very serious. It can be very frightening as you are being victimised because of who you are (or because of who or what your attacker thinks you are). Hate crime can quickly lead to tension in an overall community. Report it early to the Police to try and stop the problem quickly before it gets worse. Since a hate incident or hate crime is taken much more seriously than non-targeted anti-social behaviour, you should find that the Police are able to give you more support as they will probably have more resources available to investigate it.
There are a number of organisations working together to help victims of hate crime. The Association of Chief Police Officers has a helpful website about hate crime here: http://www.report-it.org.uk/what_is_hate_crime. The Police should know of any local organisations in your area that can help support you.
