Somerville, New Jersey, in Somerset County, has about 14,000 residents (2024 Census Bureau estimate), and its arrests are reported to the FBI by an agency of its own. An arrest in the city leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the County Prosecutor files charges, a case in the Superior Court of New Jersey, Somerset County. This guide says who keeps each one, what it costs and who may see it, with the arrest counts the agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies and common questions.

Who Makes Arrests in Somerville
The FBI lists Somerville with an arrest reporting agency of its own, filed as Somerville Police Department. It reported 103 arrests for 2025. A city is listed separately whether the officers are the city's own or the sheriff's under contract; the FBI's list does not say which.
Outside the city, the Somerset County Sheriff's Office is the county agency. It reported 212 arrests for 2025.
The FBI's agency list also places these agencies in Somerset County: the Somerset County State Police (state police); Prosecutor in Somerset County (other).
How Many Arrests Somerville Reports
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.
- Somerville: 103 for 2025, 109 for 2024, 289 for 2022, 347 for 2020 and 637 for 2019; 2021 and 2023 are missing months.
Somerville's 103 arrests in 2025 were down 5.5 percent from 109 in 2024.
Through September 2026, Somerville reported 76 arrests, against 74 in the same months of 2025.
Across Somerset County, the 18 agencies with all twelve months of 2025 on file reported 2,566 arrests between them.
Booking: Where People Arrested in Somerville Are Held
A person kept in custody after an arrest in Somerville 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 2020 the jail held about 120 people, down from about 200 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 439 beds, and it ran at 46 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Somerset County Sheriff's Office at somersetcountysheriff.com (page title: Somerset County Jail Roster Lookup, PA, Inmate Search), a site that blocks automated checks (HTTP 403), so open it in a browser.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A sentence of more than a year is served in state prison; the New Jersey Department of Corrections lists its inmates at www20.state.nj.us/DOC_Inmate/inmatefinder?i=I.
How to Find Out About an Arrest in Somerville
Whether someone was arrested in Somerville, and what came of it, shows up in three places: the custody page of the Somerset County Sheriff's Office described above, for anyone booked into the county jail; New Jersey Courts Public Access, the Judiciary's free online case search for civil and criminal cases, which shows whether charges were filed; the County Prosecutor, which decides whether an arrest becomes a charge (its page is at somersetcountynj.gov/Home/Components/FacilityDirectory/FacilityDire..., phone (908) 575-3300).
New Jersey does not let the public search another person's statewide criminal history. The record kept by the New Jersey State Police goes to the person it belongs to and to employers and agencies the law authorizes; for everyone else the court's own case index is the public record of an arrest that led to a charge.
Getting a Copy of an Arrest Record in Somerville
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 Open Public Records Act the agency must answer within 7 business days, and it may charge copying at 5 cents a page for letter size.
