You should call 101 to report crime and other concerns that do not require an emergency response.
For example, if: There are people and groups who can help if you have been the victim of a crime.
In England and Wales, you can phone Victim Support on 08 08 16 89 111 or visit the Victim Support website.
In Northern Ireland, you can phone Victim Support NI on 028 9024 3133 or visit the Victim Support NI website.
If you want to report a crime, but you do not want to be identified to the police, call Crimestoppers on 0800 555 111.
Crimestoppers will ask questions about the crime you have information on but will never ask questions about you.
If you are at all concerned your call could be traced, reassure yourself by dialling 141 before 0800 555 111, which blocks your phone number. Because Crimestoppers is an 0800 number, calls are free from a landline and don't show up on a BT or cable phone bill.
Alternatively, you can report a crime anonymously with Crimestoppers online.
The first step is to speak to members of your local neighbourhood policing team (their details are available from their neighbourhood page; search for your team with the search button at the top of this page).
These teams work closely with residents to help stop anti-social behaviour, so they need to know what's happening in your area.
If you've been the victim of a crime or think you have witnessed one, you should report it to the police straight away.
Your information could be used to prevent other crimes and help keep other people safe.
