Fort Collins, Colorado, in Larimer County, has about 171,000 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 Larimer 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 Collins Are Held
The county jail is where a person arrested in Fort Collins 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 510 people, up from about 510 in 2019. Its rated capacity in 2025 was 543 beds, and it ran at 93 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 Collins
For Fort Collins the place to look is the case index of the Larimer 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/larimer-county, phone 970-494-3500).
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 Collins
An arrest report belongs to the agency whose officer wrote it, and that agency releases it, not the court or the jail. 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.
