Investigation process

Summary

The primary purpose of a criminal investigation is to identify suspects and bring them to justice through a professional and ethical process. Investigators are tasked with managing threats, risks, and harms while ensuring safeguarding for victims and witnesses. This APP outlines a systematic approach to investigations, emphasizing the importance of proportionality, ethical standards defined by the Criminal Procedure and Investigations Act (CPIA), and the vital nature of effective crime recording. Officers are reminded that every investigation presents a unique opportunity to foster public confidence in policing and the justice system by understanding the impact of crime on communities and engaging with victims, witnesses, and suspects with empathy and professionalism.
