Which Agency Holds a Report from Roselle Park
The report of an incident is released by the agency that took it; the court and the jail hold their own records of the same event, but not the report.
Inside Roselle Park that is the agency that reports to the FBI for the city (filed by the FBI as Roselle Park Police Department); outside it, the Union County Sheriff's Office.
The FBI's list also places the Union County State Police in Union County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's list also carries Kean University (campus police) and Prosecutor in Union County and the Union County Park Police (other agency), each with a records office of its own.
