In some cases, the police deem that there is no basis for investigating the matter, for example, because it is not a criminal offence. The police will then dismiss the report, and the case will be closed.
The police may also decide to discontinue investigations. This might occur if the perpetrator proves impossible to locate, and there are no more leads to pursue.
If you are a victim of crime, you will be notified of the police's decision not to open an investigation or to discontinue one. You can file a complaint against such a decision, and you will receive guidance on how to file a complaint along with the decision.
