Can I complain without going through the formal complaints process?

Yes, you can make an 'expression of dissatisfation.'

This is for less serious cases where you might want to voice dissatisfaction about police conduct, receive an explanation or ask for information. These are dealt with by local police staff who will work to address your concerns and provide a satisfactory resolution.

To make an expression of dissatisfaction, contact any police station by mail, phone or in person. Write or speak to the officer in charge of the police station. Every effort will be made to resolve the matter without delay.
