The department consists of:

Crime Scene Investigation Unit

The role of a Crime Scene Investigator (CSI) is to attend crime scenes to search for forensic and fingerprint evidence. The CSI also produces photographic and video evidence of crime scenes. This evidence supports criminal investigations and it may lead to the identification of an offender.

The Fingerprint Development Unit supports crime scene investigations by developing and photographing fingerprints on various surfaces. The Unit can also forensically examine footprints and documents.

Fingerprint Bureau

The Fingerprint Bureau is responsible for processing finger marks submitted by Crime Scene Investigation and the Fingerprint Development Unit, and detainee fingerprints received from custody. The Bureau performs comparisons of crime scene marks and detainee fingerprints against the National Fingerprint Database (IDENT1) to establish a person’s identity and can provide expert evidence when required.

Footwear Unit

Located at Headquarters South, the Footwear Unit is responsible for processing detainee footwear impressions received from custody, and crime scene marks received by CSI. The Footwear Unit can assist with identifying an offender and linking offences together.

Imaging Unit

This includes a range of digital and graphic services, colour processing, high-quality printing and operational photographic assignments.
