About this guide

Nassau County, New York, has about 1.4 million residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Nassau County Police Department, 21 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 Nassau 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.

Booking: Where People Arrested in Nassau County Are Held

A person kept in custody after an arrest in Nassau 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.

So far in 2026 the jail has held about 690 people on an average day, down from about 1,030 in 2019. Its rated capacity in 2023, the last year with a capacity figure, was 1,540 beds, and it ran at 47 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

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 Nassau County

Whether someone was arrested in Nassau County, and what came of it, shows up in two places: eCourts, the Unified Court System's free online case search (WebCivil, WebCrims and WebFamily), which shows whether charges were filed; the District Attorney, which decides whether an arrest becomes a charge (its page is at nassaucountyny.gov/3427/Prosecution).

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 Nassau 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 Nassau County Police Department: ask its records unit.
  • An arrest in Hempstead, Freeport, Long Beach, Glen Cove, Rockville Centre, Garden City 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 United States Merchant Marine Academy or the Old Westbury State University of New York Police: the records office of the agency involved.
  • A defendant who has been charged gets the report through the case: the District Attorney handles discovery for pending cases.
  • Any county record that is not posted: the county records request page SearchSystems verified is at nassaucountyny.gov (page title: COUNTY OF NASSAU STATE OF NEW YORK APPLICATION FOR PUBLIC ACCESS TO RECORDS).
  • Your own statewide record: a fingerprint-based Record Review through the Division of Criminal Justice Services.

Cities in Nassau County: Who Reports the Arrests

The FBI lists a separate arrest reporting agency for 21 of the 66 cities in Nassau County: the twelve named above and Muttontown, Port Washington North, Brookville, Lake Success, Sands Point, Oyster Bay Cove, Old Brookville, Kensington and Centre Island. Valley Stream, Mineola, Massapequa Park, Westbury, New Hyde Park, East Rockaway, Farmingdale, Great Neck Plaza, Williston Park, Cedarhurst, East Hills, Manorhaven and 33 more have no separate reporting agency in the FBI's list.

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

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