Investigation Investigation process

Changed wording to Investigation Process under Allocation:

Old wording:

Some crimes may be considered less serious in policing. For example, because the sentence on conviction is low or because there is no apparent physical impact but can still have a profound effect on the victim. These crimes may also indicate a higher risk of future harm and may be precursors to more serious offending. 

New wording:

Some crimes may have been considered less serious in policing. This may be, for example, because the sentence on conviction is low or there is no apparent physical impact on the victim. These crimes, however, can still have a profound effect on the victim because of the nature of the offending. For example, persistent behavioural aspects, may make them more serious than they initially appear. They may also indicate a higher risk of future harm and may be precursors to more serious offending. 


 

Investigation > Investigative strategies CCTV

CCTV was contained within Passive data generators. This information has been updated to reflect legislative changes and presented in its own section (still subsumed under investigative strategies) to make it more easily accessible.

Investigation > Investigative strategies Passive data generators

Removed the section on CCTV. Due to the introduction of the Forensic Science Regulator Code of Practice. The development and implementation of the Code is required under section 2 of The Forensic Science Regulator Act 2021. The Code came into force on 2 October 2023. With the Code already being in place there is an imperative to bring the APP in line with the current obligations on forces/practitioners. As such, this section has been updated and moved into its own sub-section beneath passive data generators so that it is easier to find and use for practitioners.

Investigation Investigation process

Two new subsections added to investigative process.

  1. Adding a subsection called Allocation, after crime and incident recording, before initial engagement. The section is five paragraphs and a reference. It covers how a force can decide which person/team investigates a crime.

     

  2. Adding a subsection after jurisdiction and ownership but before Golden Hour - called Linked series crimes. It is four paragraphs in length. It advises officers and staff not to neglect less serious offences when thinking about series crimes and advises on communication across forces, including investigative strategy development and assignment.
