Lead Investigator - Core Investigations and Major Investigations (MI)

Overview

As a Lead Investigator, you will be part of a dynamic investigations team working locally and nationally on a wide range of investigations often in the public eye within the Investigation, Oversight and Casework directorate. You will lead all aspects of an investigation, from setting out the initial terms of reference, to collecting evidence, interviewing witnesses, drawing conclusions, and writing a final report, many of which are published. Reports may include recommendations for the police force or Police and Crime Commissioner about actions to be taken to improve practice and prevent mistakes in the future. After the investigation, investigations staff are responsible for supporting criminal, disciplinary and coronial proceedings which may follow.

The role requires a cultural knowledge accountability approach to work to produce rounded and robust outcomes. An on-call function outside normal hours is required, with an appropriate allowance paid under IOPC policy.

The IOPC is a public service committed to ensuring equal service and developing a diverse, socially aware workforce. The role is exempt from the Rehabilitation of Offenders Act 1974; therefore, a standard Disclosure and Barring Service (DBS) check will be carried out for the successful candidate during the pre-employment process.
