Fort Lupton, Colorado, in Weld County, has about 9,900 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 Weld County District Court. 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.

Booking: Where People Arrested in Fort Lupton Are Held
The county jail is where a person arrested in Fort Lupton 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.
On an average day in 2025 the jail held about 590 people, down from about 740 in 2019. Its rated capacity in 2025 was 1,068 beds, and it ran at 56 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 Fort Lupton
Whether someone was arrested in Fort Lupton, and what came of it, shows up in two places: the case index of the Weld County District Court, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at coloradojudicial.gov/courts/trial-courts/weld-county, phone (970) 475-2400); the District Attorney, which decides whether an arrest becomes a charge (its page is at weld.gov/Government/Elected-Officials/District-Attorney, phone (970) 400-4750).
Colorado is one of the states that lets anyone look up another person's statewide criminal history: the state runs an online name-based criminal history check open to the public, through the Colorado Bureau of Investigation. 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 Fort Lupton
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 Colorado Open Records Act the agency must answer within 3 working days, extendable to 7 when there are extenuating circumstances, and it may charge research and retrieval time after the first hour, plus copying.
