In an emergency always call 999
An emergency is when a crime is happening, someone suspected of a crime is nearby, or someone is injured, being threatened or in danger.
e.g. - If your house is being burgled (or the suspect is nearby) call 999
If your car is being stolen (or the suspect is nearby) call 999

If it’s not an emergency call 0300 123 1212
You need to report a crime that has occurred.
