There are 43 police forces across England and Wales.
They are responsible for investigating crime, collecting evidence and arresting or detaining suspected offenders.
For less serious offences the police will make the decision about whether a suspect should be charged. For more serious offences the police will send the case to the CPS and we will make a decision about whether a suspect can be prosecuted.
You can find more information about the police, including information about your local force on the police website: police.uk
