This allows, for example, the court to erect a screen between you and the defendant or for you to give evidence by a video link. Detailed guidance on the many special measures available to protect witnesses is provided on the Crown Prosecution Service website

The police investigation into the crime should begin immediately after you report it. By law, the police must regular updates (at least monthly) about your case. They must also tell you if someone is arrested and charged for the crime, and provide clear information about whether you qualify for aid from the Criminal Injuries Compensation Authority .

No, you do not have to provide a statement if you do not want to. But if you fail to provide one the police may not be able to investigate the crime. If you feel uneasy about making a statement, you should know that you do not have to give it immediately. Another thing to note is that after you have made and signed your statement, it may become part of the prosecution case and all parties involved in the case, including the accused, will be able to read it.

Yes. Every citizen has the right to bring a private prosecution to enforce criminal laws. If you suffered an injury, property damage, or theft as a result of a crime, you may also be able to sue the perpetrator for compensation -- even if he or she is acquitted of all criminal charges.
