Calling Crimestoppers is an anonymous method of reporting crime. This means that the person you speak to at Crimestoppers does not know who you are and has no way of finding out who you are.
Crimestoppers has no caller line display, no 1471 facility and no ability to trace your call. You will not be asked for your name or for any other details. The person answering the call will not even record whether it is a male or female voice calling in.
If you call from a call box or from a landline the call will not even be recorded on any bill.
The same level of anonymity goes for online reports. Crimestoppers does not have the ability to access your IP address if you fill in the online form and so no-one can trace the email to you.
Neither Crimestoppers nor the Police will ever reveal whether a case was solved using information that came from Crimestoppers – so there really is no way that your report can ever be linked back to you.
It really is a safe way of giving information.
