Forensic Science is the application of all scientific knowledge for the purposes of law, enforcement and administration of justice through use of scientific evidence or material evidence or physical evidence or objective evidence which is available in the form of physical living or no living material which is superior to personal evidence or subjective evidence that is required to prove the guilt or innocence of the suspects in criminal, civil, statutory, regulatory investigative matter and trials.

The Forensic Science Laboratory (FSL) is an organisation where the scientists of various specialities undertake laboratory tests on a variety of evidence materials with a sole objective of linking the crime with the criminals, victims and crime scene.

FSL thus provides a comprehensive scientific service from crime scene processing to evidence collection, forensic analysis, report and expert testimony in the courts.

There are many disciplines and departments within a forensic science laboratory viz. Physics, Chemistry, Toxicology, Narcotics & Drugs, Biology, Serology, DNA, Cyber, Audio-Video, Documents, Fingerprints, Engineering, Ballistics, Crime Scene Processing, Linguistics, Forensic Accounting etc.
