Which Agency Holds a Report from Delaware 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 Delaware County that is the Sheriff's Office | Delaware County, Pennsylvania 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 Delaware County State Police in Delaware 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 three state agencies, three other agencies and three campus police departments in Delaware County, each with a records office of its own.
