Knox County, Maine, has about 41,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Knox County Sheriff's Office and four city agencies. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the District Attorney files charges, a case in the Knox County Superior Court. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

Who Makes Arrests in Knox County
The Knox County Sheriff's Office is the county agency that reports arrests to the FBI for Knox County. It reported 403 arrests for 2025.
The FBI lists one city in Knox County with a reporting agency of its own:
- Rockland, 7,060 residents: 478 arrests reported for 2025.
A city on that list is reported separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
How Many Arrests Each Agency Reports in Knox County
The FBI publishes every agency's monthly arrest counts on the Crime Data Explorer. These are the full-year totals, all offenses, as the FBI held them on October 8, 2026; a year with months missing or not reported is left out.
- Rockland: 478 for 2025, 366 for 2024, 125 for 2023, 184 for 2020 and 311 for 2019; 2021 and 2022 are missing months.
- Knox County Sheriff's Office: 403 for 2025, 391 for 2024, 294 for 2023, 203 for 2022, 452 for 2020 and 413 for 2019; 2021 is missing months.
- Camden: 55 for 2025, 34 for 2024, 12 for 2023, 15 for 2022, 8 for 2021 and 24 for 2020.
- Rockport: 15 for 2025, 46 for 2024, 65 for 2023, 58 for 2022, 44 for 2021 and 34 for 2020.
- Thomaston: 33 for 2024, 17 for 2023, 8 for 2022, 19 for 2021, 39 for 2020 and 51 for 2019.
Together, the four agencies with all twelve months of 2025 on file reported 951 arrests that year. The same agencies with both 2025 and 2024 complete reported 951 in 2025 against 837 in 2024, up 14 percent.
Through April 2026, the three agencies with every month so far on file reported 225 arrests, against 293 in the same months of 2025.
Thomaston reported only part of 2025 (10 months) and is left out of the totals.
Booking: Where People Arrested in Knox County Are Held
A person kept in custody after an arrest in Knox County is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2019 the jail held about 57 people. Its rated capacity in 2019 was 70 beds, and it ran at 81 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Knox County
An arrest in Knox County can be traced in two places, depending on where the case stands: the case index of the Knox County Superior Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at courts.maine.gov/courts/superior/knox-sc.html, phone (207) 594-2576); the District Attorney, which decides whether an arrest becomes a charge (its page is at knoxcountymaine.gov/county_departments/district_attorney/overview.php, phone (207) 594-0424).
Maine is one of the states that lets anyone look up another person's statewide criminal history: conviction records are public and can be requested on anyone by name, through the Maine State Police State Bureau of Identification. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Knox County
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Maine Freedom of Access Act the agency must answer within a reasonable time, after acknowledging the request within 5 working days, and it may charge staff time after the first two hours, plus copying.
- An arrest by the Knox County Sheriff's Office: ask its records unit, reached through the office at 888-868-4631.
- An arrest in Rockland: the records unit of the agency that reports for that city; the city guides linked above name each city's records office.
- A defendant who has been charged gets the report through the case: the District Attorney, (207) 594-0424, handles discovery for pending cases.
- The court file of a case that was filed: the Knox County Superior Court, through the court records page at courts.maine.gov/courts/superior/knox-sc.html, phone (207) 594-2576.
- Any county record that is not posted: the county records request page SearchSystems verified is at knoxcountymaine.gov (page title: Knox County, ME).
