The circumstances around every crime are unique, so the way we investigate each one can vary. However, every investigation will start with the same basic steps to make sure we gather all the relevant information and keep you informed.
Find out below what happens after you report a crime, when you can expect a crime reference number and how often we’ll contact you.
The investigation process
First, we’ll make sure that we’re the correct police force to investigate the crime you've reported. For example, if it took place in a train station, this would be a matter for British Transport Police (BTP). In this case, we'd send them your report and they'd continue the investigation.
Once we’ve established we’re the correct police force, we’ll issue you with a crime reference number. How quickly we can do this depends on the complexity of the incident and number of other authorities involved.
Next, an officer will conduct an initial investigation. This could involve:
talking to witnesses
assessing the scene of the crime
reviewing CCTV or video footage
gathering other evidence such as forensic samples
searching our intelligence database
We’ll then carry out an ‘investigative assessment’. This is where we review all of the information we've gathered and decide whether to investigate your report further.
We base our decision on three key factors:
severity of the offence
likelihood it can be solved
resources needed to investigate it
There are two possible outcomes to an investigative assessment. Once we’ve made a decision, an officer will contact you to explain and offer any advice, if needed.
1. The investigation will be closed
If we decide to close the investigation, it’s probably because we've completed our initial steps and there are no further leads we can proportionately follow at that time.
Sometimes we receive new information or discover new evidence, in which case we can reopen the investigation and send you an update.
Regardless of whether this happens, your report and the information we gather as part of the investigation will become a vital part of how we police. It helps decide where and when we use police resources to detect and prevent crime.
2. Your case will be investigated further
If we decide to look into your case further we’ll assign an investigating officer to you. They’ll act as your single point of contact during the investigation, answering any of your questions and keeping you updated as the case progresses.
If you need to provide a statement, they’ll talk you through it.
In the unlikely event you need to go to court, they’ll introduce you to a member of the Witness Care Unit who'll guide you each step of the way.
