Investigating sexual crime and Operation Soteria – transforming the way rape and serious sexual assault is investigated and prosecuted in England and Wales

Operation Soteria CPD training – 6 December 2023


  • Led by Dr Patrick Tidmarsh, a member of the Operation Soteria team developing Learning and Development, for improving the investigation of rape and sexual offences across England and Wales.


  • Patrick is an internationally recognised authority in understanding and responding to sexual offending, and lectures and trains law enforcement across the world. He spent 20 years working in sex offender treatment programmes, gaining an understanding of offender behaviour, which understanding forms the basis of the Whole Story approach to investigating sexual crime, now part of the National Operating Model introduced by Operation Soteria.



Victim-Centred – Suspect-Focused – Context-Led


This workshop will focus on key elements of effective sexual crime investigation, including: Understanding offenders and grooming, eliciting relevant evidence, Whole Story investigations, and critical communication skills. It will highlight effective approaches to sexual crime investigation, and take participants through the “Investigators’ Journey”, a guide to the new National Operating Model (NOM).


Participants will be guided through the Learning and Development products and processes that are currently available, including: the online course for investigators new to RASSO (RISDP), the new online First Responders course, as well as how to access the NOM best practice guides.


The day will cover key elements of the new Learning and Development processes, including audio-visual and practical examples, focusing on the Knowledge, Attitudes, and Skills required to be an effective sexual crime investigator.


This workshop will also outline the key aspects of Operation Soteria, its findings and recommendations, and the transformative new approach to rape and serious sexual assault investigations and prosecutions set out in the NOM. The result is a process that improves support for victims, and their unique experience, before putting the investigative focus on suspects.


Operation Soteria is unique in that it brings together forces, prosecutors, and academics, to use evidence and insight to change the way rape and sexual offences are dealt with. The Home Office funded project was piloted in 5 forces, and has now been rolled out across all 43 police forces, in England and Wales.


Who should attend?

This workshop is aimed at investigators and analysts working in non-specialist roles in major crime. It is designed to provide those working in an operational role with an introduction to the investigation of sexual crime, and a sound working knowledge of Operation Soteria and the National Operating Model.


Outline of the day

  • The challenges of investigating sexual offending - understanding sexual offenders and the dynamics of sexually abusive ‘relationships’.

  • Understanding relevant evidence in RASSO – Whole Story investigations.

  • A look at how suspect-focused and victim-centred approaches can bring about culture changes in rape investigations and prosecutions.

  • The new National Operating Model and the ‘Investigators’ Journey’

  • How the NOM will be used, with predicted impacts on investigations and prosecutions.

  • An overview of Operation Soteria, its origins and the research that led to its inception.

  • Practical steps and advice for investigators on how they can implement Soteria in their investigations and how it will impact their work.


Learning objectives

The aim of our workshop is to ensure that all investigators and analysts who are working in a non-specialist role are provided with an insight into the key concepts behind Operation Soteria.
