Which Agency Holds a Report from Cambridge
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
Inside Cambridge that is the agency that reports to the FBI for the city (filed by the FBI as Cambridge Police Department); outside it, the Middlesex Sheriff's Office, MA | Official Website.
The FBI's list also places the Middlesex County State Police in Middlesex County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's agency list also places 12 campus police departments and one state agency in Middlesex County, each with a records office of its own.
