Reviewed and updated October 9, 2026 by the SearchSystems.net editorial team. The arrest and crime counts are the ones each agency reported to the FBI, as the FBI held them on October 8, 2026.

Plymouth County, Massachusetts, has about 542,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Plymouth County depends on where the incident happened: the Plymouth County Sheriff’s Department - MA POST Commission for the unincorporated county, the agency that reports for the city inside a city. This guide names each agency, where its records page is and what the Massachusetts Public Records Law requires of it.
This guide covers which agency, the sheriff's reports, the cities' reports, how many reports, what the law requires and common questions.

Which Agency Holds a Report from Plymouth County
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.
In Plymouth County that is the Plymouth County Sheriff’s Department - MA POST Commission for the unincorporated county and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
The FBI's list also places the Plymouth County State Police in Plymouth County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's list also carries Bridgewater State University and Massasoit Community College (campus police) and the Plymouth County Massachusetts Bay Transportation Authority (state agency), each with a records office of its own.
Reports from the Plymouth County Sheriff’s Department - MA POST Commission
Its reports come from its records unit. The office's page SearchSystems verified is its jail page, at mapostcommission.gov/current-agency/plymouth-county-sheriffs-depart... (page title: Plymouth County Sheriff’s Department | MA POST Commission), 84 State Street, 2nd Floor, Boston, MA 02109, which answered when SearchSystems opened it on October 9, 2026.

Any other county record goes through the county records request page SearchSystems verified, at plymouth-ma.gov/894/Public-Records-Requests (page title: Public Records Requests | Plymouth, MA).
