About this guide

Westchester County, New York, has about 1.0 million residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by 38 city agencies and three campus, state or other 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 Westchester 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 Westchester County Are Held

A person kept in custody after an arrest in Westchester 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 550 people on an average day, down from about 1,020 in 2019. Its rated capacity in 2023, the last year with a capacity figure, was 1,808 beds, and it ran at 39 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 sheriff's office at correction.westchestercountyny.gov/westchester-inmate-search (page title: Westchester Inmate Lookup), which answered when SearchSystems opened it on September 23, 2026.

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 York State Department of Corrections and Community Supervision lists its inmates at nysdoccslookup.doccs.ny.gov.

How to Find Out About an Arrest in Westchester County

An arrest in Westchester County can be traced in three places, depending on where the case stands: the custody page of the sheriff's office described above, for anyone booked into the county jail; the case index of the Westchester County Supreme and County Courts, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at westchesterclerkny.gov/legal-division/search-court-records, phone (914)995-3075); the District Attorney, which decides whether an arrest becomes a charge (its page is at newrochelleny.gov/facilities/facility/details/Westchester-County-Di...).

Statewide, eCourts is the Unified Court System's free online case search (WebCivil, WebCrims and WebFamily).

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 Westchester County

An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. 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 in Yonkers, New Rochelle, Mount Vernon, White Plains, Harrison, Port Chester 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 Westchester County, Hillview New York City Department of Environmental Protection Police, the Westchester County, Croton-Kensico New York City Department of Environmental Police or the Purchase 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.
  • The court file of a case that was filed: the Westchester County Supreme and County Courts, through the court records page at westchesterclerkny.gov, phone (914)995-3075.
  • Your own statewide record: a fingerprint-based Record Review through the Division of Criminal Justice Services.

Cities in Westchester County: Who Reports the Arrests

The FBI lists a separate arrest reporting agency for every one of the 29 cities in Westchester County: the twelve named above and Tarrytown, Dobbs Ferry, Sleepy Hollow, Rye Brook, Hastings-on-Hudson, Croton-on-Hudson, Pelham (village), Briarcliff Manor, Pleasantville, Tuckahoe, Larchmont, Irvington, Bronxville, Elmsford, Ardsley and Buchanan. Mount Kisco and Pelham Manor have no separate reporting agency in the FBI's list. The FBI's list also carries the Yorktown Town Police Department, the New Castle Town Police Department, the North Castle Town Police Department and six more as city agencies in Westchester County; Yorktown Town, New Castle Town, North Castle Town and six more 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 Westchester County Supreme and County Courts.

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