What the Mercer County Blotter Shows
The police blotter in Mercer County is a log of activity. Each entry captures the basics of an event. It is not a detailed report. The blotter tells you what happened, when, and where.
Entries on the Mercer County police blotter typically include the date and time, the street or block where the incident occurred, the nature of the call, and any arrests made. Arrest entries list the suspect's name, age, charges, and sometimes bail status. Traffic accidents, thefts, assaults, drug arrests, and warrant pickups are all common entries. The blotter gives the community a window into daily police activity across Mercer County without revealing sensitive investigative details.
Note: For the full police report behind any blotter entry, you must file a separate OPRA request with the relevant Mercer County police department.
Mercer County Arrest Record Details

It includes the person's full name, date of birth, home address, charges, and the name of the arresting officer. The date and time of the arrest are also recorded.

If an agency denies access, file a complaint with the GRC or take the matter to Superior Court. The burden falls on the agency to justify any denial. Most Mercer County departments comply with blotter requests without issue. The law is well established and agencies generally follow it.
