Crimestoppers provides a way to give information about a crime without revealing their identity.
If you have information you'd like to pass on, perhaps something you've seen or heard, all you have to do is call 0800 555 111 or report it online.
It's anonymous so you won't be asked your name, your call will not be traced or recorded and you don't have to give a statement or go to court.
Every call is treated with absolute anonymity and rewards are sometimes available if your information leads to a conviction. Rewards are paid without compromising your anonymity.
Crimestoppers is an independent charity which is an effective partnership between the local community, the police (who act on information given by callers) and the media.
The organisation relies on around 600 volunteers to help take calls and provide community safety advice.
Formed in 1988, Crimestoppers started because many people feared retribution if they were to come forward to the police with information about crimes. By helping to break the wall of silence, more criminals can be brought to justice and more crimes can be prevented.
The charity's promise of anonymity has never been broken.
