If you want to give information about a crime or incident but you do not want to tell the Police who you are, or provide an official statement, then you can call Crimestoppers on 0800 555 111. Alternatively you can fill in an online form so you do not even have to speak to anyone. Click here to fill in an encrypted form that cannot be traced back to you, with as much information as you have.
You may wish to clear your internet history afterwards. This can be done in Internet Explorer by clicking > Tools > Options > Under Browsing History click Delete > Delete History (and any other appropriate options) > OK
