Scientific Support Unit (SSU)

Our Scientific Support Unit uses cutting-edge technology to examine forensic evidence collected at the scene of a crime, fatality or incident to help piece together what happened.

Crime Scene Examiners

Our Crime Scene Examiners (CSEs) attend crime scenes and recover forensic evidence such as fingerprints, DNA and footwear impressions. They also take photographs at crime scenes.

Crime Scene Co-ordinators oversee complex crime scenes while Crime Scene Managers are responsible for specific crime scenes and investigations. CSEs attend all crime scenes when required, assist in property recovery and deploy to specific operations.

Central Submissions

Once it has been collected, evidence is taken to our Central Submissions unit. Central submissions look at every case and decide which forensic process should be applied, either externally or internally.

Examination in the lab

Our laboratories screen evidence for biological fluids (eg. blood, saliva etc) and use various chemicals to enhance fingerprints on items recovered from crime scenes. Most evidence is examined in the lab, although our lab staff occasionally go out to scenes to process items that cannot be moved.

Taking fingerprints and DNA

When a suspect is brought into custody, their DNA and fingerprints are taken by officers and sent to our Forensic Custody unit, who replicate all forensic samples that have been collected.

All fingerprints collected at the scene of a crime or incident are passed to our Fingerprint Bureau. The bureau compares fingerprints found at crime scenes with those held on record to identify offenders.

Photographing evidence

The specialist photographers in our Photography unit take images of evidence to be used in investigations or court cases.

Hi-tech Crime

The Hi-tech Crime unit examines digital evidence found on computers, mobile phones, SIM cards, memory devices, sat-navs, digital cameras and gaming consoles. 

These devices can be scanned for photographs, documents and other data, without affecting the data that is stored on the device. This evidence can then be stored so that it can be used in court.
