Major and Organised Crime Department

Young male in cell holding his headThe Major and Organised Crime Department (MOCD) contains specially trained detectives who investigate complex investigations including murder, manslaughter, kidnap, stranger abduction, blackmail, product contamination, and work-related deaths, the department also targets organised criminals such as drugs dealers and money launderers.

The majority of investigations involve the setting up of an incident room which becomes the base for a team of officers and police staff dedicated to a particular investigation. All information which comes into an incident room is entered on the powerful HOLMES 2 computer system, (Home Office Large Major Enquiry System), so it can be easily researched, retrieved and compared. It provides technological support to manage the large amount of information collated during a major investigation. This categorises evidence, information and intelligence to ensure that nothing is overlooked or duplicated, and that enquiries are effectively prioritised.
An investigative strategy is drawn up by the Senior Investigating Officer (SIO), a Detective Chief Inspector or Detective Inspector. The SIO has responsibility for managing the investigation from its outset until it reaches court. They establish the main lines of enquiry and ensures that the investigation is properly resourced.
The incident room is managed day-to-day by a Detective Sergeant who oversees a team of other detectives and police staff. Other officers are specialists in areas such as managing exhibits, family liaison, file preparation and interviewing witnesses and suspects. There are also enquiry teams of detectives who follow inquiries and gather the information needed for a particular case.
All of the department's officers are nationally accredited under a government scheme and are continually involved in professional development to keep their skills up-to-date with the latest techniques and legislation.
From the outset of investigations, the team works closely with the Crown Prosecution Service to ensure that successful prosecution cases can be built in accordance with evidential rules and court timescales.
