The Investigation Division is comprised of the Detective Bureau, the Domestic Security Unit, the Youth Services Unit, the Identification Unit and the Firearms Unit.

The Detective Bureau is responsible for investigating crimes, including processing crime scenes and collecting evidence, providing technical and operational support and coordinating investigations with personnel from various Federal, State and County law enforcement agencies.  Typical investigations include robberies, sexual assaults, arsons, burglaries, motor vehicle and other thefts, missing persons and all juvenile related criminal activity.    They also perform additional responsibilities such as liaisons with local law enforcement agencies, permit and license inspections, gathering and disseminating intelligence, personal background checks, and numerous other duties. 

Detectives combat crime by conducting prompt and diligent investigations. Detectives maximize the use of all available technological resources and traditional investigations methods to solve crimes, track down and apprehend suspects, accomplices and fugitives, as well as to locate missing persons and stolen property. Today’s detectives combine traditional investigative savvy, legwork, meticulous collection of physical evidence and interrogation skills with the ability to use the latest in communications and computer technology to work a case.

The Domestic Security Unit is responsible for maintaining daily contact with the Federal, State and County agencies involved in providing domestic security and with disseminating relevant information to specific personnel within the Department.

The Youth Services Unit is responsible for working closely with the State and County youth services agencies, local schools and parent groups, and other organizations to prevent juvenile crime and to identify those juveniles who are in need of help.  The School Resource Officer (SRO) serves as the primary juvenile officer and plays a vital role in helping our youth through daily contact with students of all ages in our borough schools.

The Identification Unit is responsible for processing and maintaining all fingerprint and mug shot records, as well as maintaining regular liaison with the State Identification Unit.

The Firearms Unit is responsible for processing all requests for Firearms ID Cards and Pistol Purchase Permits and for maintaining records of all firearm purchases.

The Investigation Division is staffed by a Lieutenant, a Detective Sergeant and three Detectives (including the SRO).
