The Investigative Division's primary goal is to improve the quality of life for residents, businesses and visitors to the township by conducting thorough follow-up investigations aimed at the detection, arrest, and conviction of offenders, for both crimes against persons and property. In furtherance of this goal, the division is broken down into three (3) functional investigative units; Detective Bureau, Juvenile Bureau and Identification Bureau.

The Investigative Division consists of a Captain, Lieutenant and Sergeant, four general Detectives, three Identification (ID) Detectives, and two Juvenile Detectives.  The section also has a Detective assigned as a School Resource Officer to the East Brunswick Township Public Schools.

The success of the Investigative Section is dependent upon the acceptance that the total is greater than the sum of its parts. This cooperative spirit enhances the capability of all members of the division while recognizing that the differences inherent in modern police work fortifies, rather than detracts from, the department's overall mission.
