Police science or police studies is the study of police work. It is a subfield of criminology and sociology.^[1][2] As an interdisciplinary science, the field includes contributions from political science,^[3] forensic science, anthropology, psychology, jurisprudence, criminal justice, human geography,^[4] correctional administration and penology. The field makes contributions to understanding of community policing, police culture, and other policing tactics or behaviors.

There was a "dizzying expansion" of police studies in the early 2000s with a large number of works being published in the field.^[1]

UK has developed the Police National Computer as a sophisticated intelligence tool that holds extensive data on criminals, vehicles and property, and accessible in a matter of seconds through over 30,000 terminals across the country.

PITO reports that a national fingerprint and DNA database has been developed containing over 3.4 million DNA profiles providing the police with an average of 3,000 matches a month. In 2004-5 there were over 40,000 matches.

The police use a wide range of technologies to curb road traffic offences like speeding and drunk driving including breathalyser devices, bus lane enforcement cameras, immobilisation devices, light signals devices and speed measuring devices.^[5]

A department of Criminology and Police Science (CPS) has launched in 2003 at Mawlana Bhashani Science and Technology University.
