About this guide

Suffolk County, New York, has about 1.5 million residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Suffolk County Sheriff's Office, one other county agency, 18 city agencies and two campus 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 Suffolk County Supreme and County Courts. 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 Suffolk County

The Suffolk County Sheriff's Office is the county agency that reports arrests to the FBI for Suffolk County. It reported 950 arrests for 2025.

The Suffolk County Police Department also reports arrests to the FBI as another county agency of Suffolk County.

The FBI lists 15 cities in Suffolk County with a reporting agency of their own, with the Census population and what each reported, the largest twelve first; the rest are named in the cities section below:

  • Amityville, 9,718 residents: 178 arrests reported for 2025.
  • Northport, 7,317 residents: 150 arrests reported for 2019.
  • Southampton (village), 4,693 residents: 43 arrests reported for 2024.
  • Southampton (town), 4,693 residents: 479 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.

The FBI's agency list also places these agencies in Suffolk County: the Farmingdale State University of New York Police and the Stony Brook State University of New York Police (campus police).

Booking: Where People Arrested in Suffolk County Are Held

The county jail is where a person arrested in Suffolk County and kept in custody ends up, whichever agency made the arrest, though a city department may hold someone in its own cells first and a person cited and released at the scene is never booked. The jail's record of each person held, with the charges, is a public record of the arrest, and once the person is released or sentenced the record continues in the court file.

So far in 2026 the jail has held about 1,090 people on an average day, up from about 990 in 2019. Its rated capacity in 2021, the last year with a capacity figure, was 1,793 beds, and it ran at 42 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

SearchSystems opened and checked the jail page of the Suffolk County Sheriff's Office at suffolkcountyny.gov/sheriff (page title: Suffolk County Government > Sheriff), phone (631) 852-2200, 100 Veterans Memorial Hwy P.O. Box 6100 Hauppauge, NY 11788, which answered when SearchSystems opened it on September 23, 2026.

A sentence of more than a year is served in state prison; the New York State Department of Corrections and Community Supervision lists its inmates at nysdoccslookup.doccs.ny.gov.

How to Find Out About an Arrest in Suffolk County

For Suffolk County the place to look is eCourts, the Unified Court System's free online case search (WebCivil, WebCrims and WebFamily), which shows whether charges were filed.

New York is one of the states that lets anyone look up another person's statewide criminal history: the Office of Court Administration sells a statewide search of criminal court records by name and date of birth, for $95 a search, through the New York State Office of Court Administration. 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 Suffolk 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 Freedom of Information Law the agency must answer within 5 business days, at least with an acknowledgment and a date for the full answer, and it may charge copying at 25 cents a page.

  • An arrest by the Suffolk County Sheriff's Office: ask its records unit, reached through the office at (631) 852-2200.
  • An arrest in Amityville, Northport, Southampton (village), Southampton (town), Lloyd Harbor, Sag Harbor or another of the cities listed above: the records unit of the agency that reports for that city; the city guides linked above name each city's records office.
  • An arrest by the Farmingdale State University of New York Police or the Stony Brook State University of New York Police: the records office of the agency involved.
  • Your own statewide record: a fingerprint-based Record Review through the Division of Criminal Justice Services.

The other Suffolk County guides go further: warrants, inmate search, criminal records, court records, police reports, traffic tickets, DUI and property records.

Cities in Suffolk County: Who Reports the Arrests

The FBI lists a separate arrest reporting agency for 15 of the 32 cities in Suffolk County: the twelve named above and Huntington Bay, Asharoken and Ocean Beach. Lindenhurst, Patchogue, Babylon, Lake Grove, Port Jefferson, Islandia, Brightwaters, Greenport, Bellport, Village of the Branch, North Haven, Poquott and seven more have no separate reporting agency in the FBI's list. The FBI's list also carries the Southold Town Police Department, the Shelter Island Town Police Department and the Riverhead Town Police Department as city agencies in Suffolk County; Southold Town, Shelter Island Town and Riverhead Town are not among the cities above.

Wherever in the county the arrest happens, a person kept in custody goes to the county jail and the case goes to the Suffolk County Supreme and County Courts.

SearchSystems has a guide to the offices of these cities in Suffolk County, with the 2024 Census Bureau population; a city with its own arrest records guide opens there:
