Assistant Chief Constable Major Crime and Public Protection


Temporary Assistant Chief Constable Duncan Sloan is responsible for Major Crime and Public Protection which includes Public Protection, Local Crime & Forensics and Major Crime.

Before being appointed to this role in November 2019, T/ACC Sloan was Head of Intelligence Support, the strategic lead with responsibility for supporting all Local Policing and wider Specialist Divisions in responding to current and emerging threats on behalf of the people of Scotland.

That role, which he took up in 2017, included the co-ordination of local, regional, national and international intelligence and information sharing, managing covert assets and providing technical support to other Police Scotland business areas including external (national and international) partners. Key to the role was ensuring Police Scotland is compliant with legislation and acts in accordance with the Human Rights Act.

From 2014, as a Detective Superintendent, he worked in local crime and public protection in Q Division, in MITS West, in Strategy and Innovation for Policing 2026 and, latterly, in Intelligence Support as Head of Technical Collections.

T/ACC Sloan began his career with Strathclyde Police in 1991 where he served in a variety of uniform and plain clothes roles. He worked on numerous major investigations, as an investigator, crime scene manager, interview advisor and including the first major enquiry which involved mass screening for DNA.

His work with Strathclyde Police was interspersed with roles with the Scottish Crime Squad (SCS) and the Scottish Crime and Drug Enforcement Agency (SCDEA). His roles with SCS and SCDEA included investigation into serious organised crime and training in the use of specialised covert policing techniques.

This role developed into leading a team of detectives investigating complex, often long term, international investigations into the highest echelons of serious organised criminality, and included close international co-operation.
