Forensic Services

The City of London Police's Forensic Services has been designed to meet the needs of the City of London Police but also the wider international opportunities. We are the first point of contact for knowledge and advice with regard to:

  • High Tech Crime Unit - Digital forensics
  • Fingerprint Bureau
  • Scenes of Crime
  • Coroner's Office
  • Academic Partnerships
High Tech Crime Unit - Digital forensics


​The High Tech Crime Unit consists of a team of specialist analysts and investigators trained in both the technical and legal aspects of computer crime investigation. This team is the first point of call for in-house processed or engagement with external laboratories and national organisations dealing with cyber crime. From hand-help devices to corporate servers the HTCU have the capability to recover and present evidence from a range of digital devices.



Fingerprint Bureau

​The Fingerprint Bureau, which consists of both the Bureau itself and the Fingerprint Enhancement Laboratory, has experts with over 85 years’ experience between them. They use a range of recovery techniques using state of the art technology.

The Fingerprint Enhancement Laboratory is accredited to ISO 17025 international standards and has technicians on hand that can provide both in-house and crime scene fingerprint development and recovery.

The Fingerprint Bureau is also ISO certified and has in-house experts who can provide fingerprint assessments, database searches and identification opportunities.

Scenes of Crime

​The Scences of Crime team consists of specialist scene examiners and crime scene managers to deal with the management and examination of all scenes. They recover and process all evidence types, ensuring the best possible and most meaningful evidence is obtained. Working closely with their academic and professional partners the team are aware of the most recent advances in forensic science technologies (DNA17, fluorescent powder suspension, fingerprint examinations amongst many others) and therefore are able to advise on the evidential value of exhibits and have a wide range of inhouse techniques at their disposal. They can also offer the best options for submissions to external analytical providers.

The team utilises its wealth of experience to provide a more streamlined approach to the way our business supports investigative teams. We are also able to support a covert forensic capability. We are always looking to broaden our capabilities by developing new techniques as the science behind scene examination is constantly advancing.

Coroner's Officer

​The Coroner's Officer acts as a liasion between the famillies and doctor of the deceased, as well as the pathologist, mourtuary, funeral directors, Coroner and other outside agencies.The Coroner's Officer acts as a liaison between the families and doctor of the deceased, as well as the pathologist, mortuary, funeral directors, Coroner and other outside agencies.

Academic Partnerships

​We have strong links with academia, the Forensic Science Unit at King's College London and the Jill Dando Institute at University College London are amongst Forensic Services' key academic partners; both institutions have high reputations in the field of forensic science. The Force's Director of Forensic Services, Tracy Alexander is a senior visiting lecturer at King's College and a visiting lecturer at the Jill Dando Institute of Crime Science.

Research projects run each year, looking at technological advances and the prime utilisation of this research for the City of London Police.

Director of Forensic Services

​Tracy Alexander has worked in forensic science since 1992. Her original post with the Met Police Service Directorate of Forensic Services incorporated fingerprint expertise and crime scene skills after which she progressed to working on major homicide investigations. She was the head of the Forensic Intelligence Bureau where she worked on multiple projects including the National Ballistics Intelligence Service and DNA search tools for mass fatalities.

Tracy is a council member of BAFS (British Academy of Forensic Scientists), a trustee and advisory panel member of Inside Justice and has been a member of the Chartered Society of Forensic Scientists for over 20 years.

For Inside Justice, Tracy leads the forensic reinvestigation strategy in order to address alleged miscarriages of justice. This involves examining the fundamental principles behind some of the long-established and accepted forensic practices.

Tracy is passionate about ensuring forensic techniques are available to those engaged in wildlife crime.

Tracy’s plans for the future at the City of London Police and King’s College are to work on the public relationship of their already successful academic partnership, with the establishment of City Forensics at King’s in an endeavour to encourage students to apply themselves to addressing the problems of modern policing to the mutual benefit of both organisation. This will incorporate a multi-disc forensic approach incorporating traditional practices with cyber investigation techniques created for the modern era.
