Nassau County Overview
Nassau County Police Department Records
The Nassau County Police Department is the primary law enforcement agency for the county. It covers the unincorporated areas and many of the towns and villages that do not have their own police force. That includes the Town of Hempstead, the Town of Oyster Bay, and the Town of North Hempstead, among others. The department handles a high volume of arrests each year.
To get arrest records from the Nassau County Police, submit a FOIL request. FOIL is the Freedom of Information Law under Article 6 of the Public Officers Law, sections 84 through 90. Your request should be in writing and include the person's name, date of arrest, and any report numbers you have. The department must respond within five business days. Copies cost $0.25 per page under Public Officers Law section 87.
Some villages and cities in Nassau County have their own police departments. Long Beach, Glen Cove, and a few others run independent forces. If the arrest happened in one of those areas, you need to contact that department directly. The Nassau County Police will only have records for arrests their officers made.
Nassau County Sheriff and Jail
The Nassau County Sheriff's Office handles incarceration records, pistol permits, and civil process. If someone is in the Nassau County jail, the Sheriff's Office can tell you about their custody status, charges, and bail. The jail holds pre-trial detainees and people serving short sentences.
For inmate information, contact the Sheriff's Office during business hours. Visiting rules and hours change, so call ahead. All mail to inmates needs the full name and booking number. People arrested in the last 72 hours may still be in police processing and not yet in the jail system. If someone was transferred to state prison, use the DOCCS Inmate Lookup.
