Lockport, New York, in Niagara County, has about 20,000 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 District Attorney files charges, a case in the Niagara County Supreme and County Courts. 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 Lockport
The FBI lists Lockport with an arrest reporting agency of its own, filed as Lockport Police Department. It reported 512 arrests for 2020, its latest complete year. 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 Niagara County Sheriff's Office is the county agency. It reported 597 arrests for 2025.
How Many Arrests Lockport Reports
Each agency reports its arrests to the FBI by month, and the FBI publishes them 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.
- Lockport: 512 for 2020.
Across Niagara County, the eight agencies with all twelve months of 2025 on file reported 2,830 arrests between them.
Booking: Where People Arrested in Lockport Are Held
A person kept in custody after an arrest in Lockport 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 400 people on an average day, up from about 350 in 2019. Its rated capacity in 2019, the last year with a capacity figure, was 505 beds, and it ran at 69 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.

How to Find Out About an Arrest in Lockport
An arrest in Lockport can be traced in two places, depending on where the case stands: the case index of the Niagara County Supreme and County Courts, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at niagaracounty.gov/departments/a-f/county_clerk/index.php, phone 716-439-7022); the District Attorney, which decides whether an arrest becomes a charge (its page is at niagaracounty.gov/departments/a-f/district_attorney/index.php, phone (716) 439-7085).
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.
