Frederick County, Maryland, has about 299,000 residents (2024 Census Bureau estimate). A police report belongs to the agency whose officer wrote it, so which office holds a report from Frederick County depends on where the incident happened: the Frederick County Sheriff's Office 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 Maryland Public Information Act 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 Frederick 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 Frederick County that is the Frederick County Sheriff's Office 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 Frederick County State Police in Frederick County; a report taken on a state highway by it comes from that agency's own records office.
The Mount Airy Police Department is listed by the FBI across two counties including Frederick County, so its arrests are not broken out for Frederick County here.
