The Orchard Park Police Detective Bureau is staffed by three detectives and its work complements the work of the patrol division.

Detective work is specialized, usually encompassing the examination and evaluation of evidence to apprehend suspects and build solid cases against them. Patrol officers often investigate misdemeanor cases such as assault, larceny, and criminal mischief. Cases requiring extensive investigation, involving serious crimes, or special victims are referred to the Detective Bureau. 

In addition to conducting investigations initiated by the Orchard Park Police Patrol Division, the Detective Bureau regularly works with other local, county, state, and federal law enforcement agencies. Investigations conducted by the Detective Bureau often include auto theft, fraud, financial crimes, child abuse, violent crimes, and other special victim crimes.
