Detective Bureau

A vital police function is the effective investigation of reported crimes. The goal of any police investigation is to successfully identify and bring criminal offenders before the court. Many times this is accomplished by the patrol officer, the backbone of all law enforcement agencies. When the crime reported is of a serious nature, or requires extended investigation, a detective will be assigned to the case.

A Detective is a police officer who has received specialized training to further investigate and help prosecute reported crimes that may require extended investigation. The Westfield Police Department Detective Bureau is responsible for these investigations when the crimes reported are alleged to have taken place in Westfield. The narcotics unit also falls within the scope of the Detective Bureau.
