The Detective Bureau of the Red Bank Police Department conducts follow-up investigations of crimes reported to the police department. All initial crime reports are reviewed by a supervisor in the detective bureau and are assigned for follow-up investigation based on several solvability factors with priority given to more serious offenses. Personnel assigned to this unit conduct interviews of victims, witnesses, and suspects, collect and process evidence from crime scenes and prepare cases for prosecution.
Members of the Detective Bureau also manage the criminal forfeiture program, the Megan's Law registration program, conduct Alcohol Beverage Control investigations, Firearms background investigations, and pre-employment background investigations for police department applicants. Certain members of the Detective Bureau are specially trained to investigate juvenile cases. In addition to conducting these investigations, these members also coordinate diversion programs such as the Station House Adjustment Program, Juvenile Conference Committee, and central charging programs through the Monmouth County Prosecutor's Office.
